This work has been performed principally within the setting of cavity quantum electrodynamics(1-4) with diverse physical systems(5), including single atoms in Fabry-Perot resonators(1,6), quantum dots coupled to micropillars and photonic bandgap cavities(7,8) and Cooper pairs interacting with superconducting resonators(9,10). Experiments with single, localized atoms have been at the forefront of these advances(11-15) with the use of optical resonators in high-finesse Fabry-Perot configurations(16). As a result of the extreme technical challenges involved in further improving the multilayer dielectric mirror coatings(17) of these resonators and in scaling to large numbers of devices, there has been increased interest in the development of alternative microcavity systems(5). Here we show strong coupling between individual caesium atoms and the fields of a high-quality toroidal microresonator. From observations of transit events for single atoms falling through the resonator's evanescent field, we determine the coherent coupling rate for interactions near the surface of the resonator. We develop a theoretical model to quantify our observations, demonstrating that strong coupling is achieved, with the rate of coherent coupling exceeding the dissipative rates of the atom and the cavity. Our work opens the way for investigations of optical processes with single atoms and photons in lithographically fabricated microresonators. Applications include the implementation of quantum networks(18,19), scalable quantum logic with photons(20), and quantum information processing on atom chips(21).}, af = {Aoki, TakaoEOLEOLDayan, BarakEOLEOLWilcut, E.EOLEOLBowen, W.

By using high-quality resonators, a strong coupling regime can be reached experimentally in which atoms coherently exchange a photon with a single light-field mode many times before dissipation sets in. This has led to fundamental studies with both microwave(2,3) and optical resonators(4). To meet the challenges posed by quantum state engineering(5) and quantum information processing, recent experiments have focused on laser cooling and trapping of atoms inside an optical cavity(6-8). However, the tremendous degree of control over atomic gases achieved with Bose-Einstein condensation(9) has so far not been used for cavity QED.

Here we report the generation, transmission, storage and retrieval of single quanta using two remote atomic ensembles. A single photon is generated from a cold atomic ensemble at one site 1, and is directed to another site through 100 metres of optical fibre. The photon is then converted into a single collective atomic excitation using a dark-state polariton approach(2). After a programmable storage time, the atomic excitation is converted back into a single photon. This is demonstrated experimentally, for a storage time of 0.5 microseconds, by measurement of an anti-correlation parameter. Storage times exceeding ten microseconds are observed by intensity cross-correlation measurements. This storage period is two orders of magnitude longer than the time required to achieve conversion between photonic and atomic quanta.

Because only probability amplitudes are required for this task, a more efficient semiclassical version can be used, for which only single-qubit operations conditioned on measurement outcomes are required. We apply the transform to several input states of different periodicities; the results enable the location of peaks corresponding to the original periods.

In particular, scalable quantum networks require the capability to create, store and distribute entanglement among distant matter nodes by means of photonic channels(3). Atomic ensembles can play the role of such nodes(4). Sofar, in the photon- counting regime, heralded entanglement between atomic ensembles has been successfully demonstrated through probabilistic protocols(5,6). But an inherent drawback of this approach is the compromise between the amount of entanglement and its preparation probability, leading to intrinsically low count rates for high entanglement. Here we report a protocol where entanglement between two atomic ensembles is created by coherent mapping of an entangled state of light. By splitting a single photon(7-9) and performing subsequent state transfer, we separate the generation of entanglement and its storage(10). After a programmable delay, the stored entanglement is mapped back into photonic modes with overall efficiency of 17%. Together with improvements in single- photon sources(11), our protocol will allow 'on- demand' entanglement of atomic ensembles, a powerful resource for quantum information science.}, af = {Choi, K.

Such a simulation may be implemented using a well-controlled system of effective spins, such as a two-dimensional lattice of locally interacting ions. We propose here a layered planar rf trap design that can be used to create arbitrary two-dimensional lattices of ions. The design also leads naturally to ease of microfabrication. As a first experimental demonstration, we confine Sr-88(+) ions in a millimeter-scale lattice trap and verify numerical models of the trap by measuring the motional frequencies. We also confine 440 nm diameter charged microspheres and observe ion-ion repulsion between ions in neighboring lattice sites. Our design, when scaled to smaller ion-ion distances, is appropriate for quantum simulation schemes, e.g., that of Porras and Cirac [Phys. Rev. Lett. 92, 207901 (2004)]. We note, however, that in practical realizations of the trap, an increase in the secular frequency with decreasing ion spacing may make a coupling rate that is large relative to the decoherence rate in such a trap difficult to achieve.

For single atoms, this 'strong coupling regime' of cavity quantum electrodynamics(1,2) has been the subject of many experimental advances. Efforts have been made to control the coupling rate by trapping(3,4) the atom and cooling(5,6) it towards the motional ground state; the latter has been achieved in one dimension so far(5). For systems of many atoms, the three-dimensional ground state of motion is routinely achieved(7) in atomic Bose-Einstein condensates (BECs). Although experiments combining BECs and optical cavities have been reported recently(8,9), coupling BECs to cavities that are in the strong-coupling regime for single atoms has remained an elusive goal. Here we report such an experiment, made possible by combining a fibre-based cavity(10) with atom-chip technology(11). This enables single-atom cavity quantum electrodynamics experiments with a simplified set-up and realizes the situation of many atoms in a cavity, each of which is identically and strongly coupled to the cavity mode(12). Moreover, the BEC can be positioned deterministically anywhere within the cavity and localized entirely within a single antinode of the standing-wave cavity field; we demonstrate that this gives rise to a controlled, tunable coupling rate. We study the heating rate caused by a cavity transmission measurement as a function of the coupling rate and find no measurable heating for strongly coupled BECs. The spectrum of the coupled atoms-cavity system, which we map out over a wide range of atom numbers and cavity-atom detunings, shows vacuum Rabi splittings exceeding 20 gigahertz, as well as an unpredicted additional splitting, which we attribute to the atomic hyperfine structure.

These techniques are important for the practical realization of quantum networks, in which multiple memory nodes that utilize atoms for generation, storage and processing of quantum states are connected by single-photon transmission in optical fibres(1,2). One promising avenue for the realization of quantum networks involves the manipulation of quantum pulses of light in optically dense atomic ensembles using electromagnetically induced transparency (EIT, refs 8, 9). EIT is a coherent control technique that is widely used for controlling the propagation of classical, multi-photon light pulses(10-14) in applications such as efficient nonlinear optics(15). Here we demonstrate the use of EIT for the controllable generation, transmission and storage of single photons with tunable frequency, timing and bandwidth. We study the interaction of single photons produced in a 'source' ensemble of Rb-87 atoms at room temperature with another 'target' ensemble. This allows us to simultaneously probe the spectral and quantum statistical properties of narrow-bandwidth single-photon pulses, revealing that their quantum nature is preserved under EIT propagation and storage. We measure the time delay associated with the reduced group velocity of the single-photon pulses and report observations of their storage and retrieval.}, c1 = {Harvard Univ, Dept Phys, Cambridge, MA 02138 USA.EOLEOLHarvard Smithsonian Ctr Astrophys, Cambridge, MA 02138 USA.EOLEOLTech Univ Kaiserslautern, Fachbereich Phys, D-67663 Kaiserslautern, Germany.EOLEOLPN Lebedev Phys Inst, Moscow 117924, Russia.}, di = {10.1038/nature04327}, em = {eisaman@fas.harvard.edu}, ga = {990XX}, j9 = {NATURE}, ji = {Nature}, keywords = {QUANTUM COMMUNICATION; ATOMIC ENSEMBLES; LIGHT; GENERATION; STORAGE; OPTICS; MEMORY; PAIRS; GAS}, la = {English}, nr = {30}, owner = {herskind}, pa = {MACMILLAN BUILDING, 4 CRINAN ST, LONDON N1 9XW, ENGLAND}, pg = {5}, pi = {LONDON}, publisher = {Nature Publishing Group}, rp = {Eisaman, MD, Harvard Univ, Dept Phys, Cambridge, MA 02138 USA.}, sc = {Multidisciplinary Sciences}, sn = {0028-0836}, tc = {111}, timestamp = {2008.09.08}, url = {http://www.nature.com/nature/journal/v438/n7069/abs/nature04327.html}, ut = {ISI:000233777800047} } @BOOK{Emsley1995, title = {The Elements}, publisher = {Oxford University Press, New York}, year = {1995}, author = {Emsley, J.}, owner = {herskind}, timestamp = {2008.06.10} } @ARTICLE{Fischer1959, author = {Fischer, E.}, title = {Die Dreidimensionale Stabilisierung Von Ladungstragern In Einem Vierpolfeld}, journal = {Zeitschrift Fur Physik}, year = {1959}, volume = {156}, pages = {1--26}, number = {1}, owner = {herskind}, timestamp = {2008.04.30}, url = {http://www.springerlink.com/content/rv3p37027u78442k/?p=4ce1fb3bddf9421fb7ff60f260c8b803&pi=0}, ut = {ISI:A1959WQ76000001} } @ARTICLE{Fleischhauer2005, author = {Fleischhauer, M. and Imamoglu, A. and Marangos, J.

In this way the optical properties of a medium can be dramatically modified, leading to electromagnetically induced transparency and related effects, which have placed gas-phase systems at the center of recent advances in the development of media with radically new optical properties. This article reviews these advances and the new possibilities they offer for nonlinear optics and quantum information science. As a basis for the theory of electromagnetically induced transparency the authors consider the atomic dynamics and the optical response of the medium to a continuous-wave laser. They then discuss pulse propagation and the adiabatic evolution of field-coupled states and show how coherently prepared media can be used to improve frequency conversion in nonlinear optical mixing experiments. The extension of these concepts to very weak optical fields in the few-photon limit is then examined.

An adiabatic technique is suggested which allows to transfer non-classical. correlations from traveling-wave single-photon wave-packets into atomic states and vise versa with nearly 100% efficiency. In contrast to previous approaches involving single atoms, the present technique does not require the strong coupling regime corresponding to high-Q micro-cavities. Instead, intracavity electromagnetically Induced Transparency is used to achieve a strong coupling between the cavity mode and the atoms. (C) 2000 Elsevier Science B.V.

Lett. 98, 123601 (2007)], we used a universal physical picture to optimize and demonstrate equivalence between a wide range of techniques for storage and retrieval of photon wave packets in Lambda-type atomic media in free space, including the adiabatic reduction of the photon group velocity, pulse-propagation control via off-resonant Raman techniques, and photon-echo-based techniques. In the present paper, we perform the same analysis for the cavity model. In particular, we show that the retrieval efficiency is equal to C/(1+C) independent of the retrieval technique, where C is the cooperativity parameter. We also derive the optimal strategy for storage and, in particular, demonstrate that at any detuning one can store, with the optimal efficiency of C/(1+C), any smooth input mode satisfying TC gamma >> 1 and a certain class of resonant input modes satisfying TC gamma similar to 1, where T is the duration of the input mode and 2 gamma is the transition linewidth. In the two subsequent papers of the series, we present the full analysis of the free-space model and discuss the effects of inhomogeneous broadening on photon storage.}, af = {Gorshkov, Alexey V.EOLEOLAndre, AxelEOLEOLLukin, Mikhail D.EOLEOLSorensen, Anders S.}, c1 = {Harvard Univ, Dept Phys, Cambridge, MA 02138 USA.EOLEOLDanish Natl Res Fdn Ctr Quantum Opt, QUANTOP, DK-2100 Copenhagen O, Denmark.}, di = {10.1103/PhysRevA.76.033804}, ga = {215CN}, j9 = {PHYS REV A}, ji = {Phys.

However, the analogous quantum procedure (the Deutsch-Jozsa algorithm(1,2)) requires just one examination step. The Deutsch-Jozsa algorithm has been realized experimentally using bulk nuclear magnetic resonance techniques(3,4), employing nuclear spins as quantum bits (qubits). In contrast, the ion trap processor utilises(5) motional and electronic quantum states of individual atoms as qubits, and in principle is easier to scale to many qubits. Experimental advances in the latter area include the realization of a two-qubit quantum gate(6), the entanglement of four ions(7), quantum state engineering(8) and entanglement-enhanced phase estimation(9). Here we exploit techniques(10,11) developed for nuclear magnetic resonance to implement the Deutsch-Jozsa algorithm on an ion-trap quantum processor, using as qubits the electronic and motional states of a single calcium ion. Our ion-based implementation of a full quantum algorithm serves to demonstrate experimental procedures with the quality and precision required for complex computations, confirming the potential of trapped ions for quantum computation.}, c1 = {Innsbruck Univ, Inst Expt Phys, A-6020 Innsbruck, Austria.EOLEOLMIT, Media Lab, Cambridge, MA 02139 USA.}, di = {10.1038/nature01336}, ga = {631JY}, j9 = {NATURE}, ji = {Nature}, keywords = {PAUL TRAP; SPECTROSCOPY; ENTANGLEMENT; COMPUTATION; TRANSITION; STATE; ATOM}, la = {English}, nr = {22}, owner = {herskind}, pa = {MACMILLAN BUILDING, 4 CRINAN ST, LONDON N1 9XW, ENGLAND}, pg = {3}, pi = {LONDON}, publisher = {Nature Publishing Group}, rp = {Schmidt-Kaler, F, Innsbruck Univ, Inst Expt Phys, Technikerstr 25,EOLEOLA-6020 Innsbruck, Austria.}, sc = {Multidisciplinary Sciences}, sn = {0028-0836}, tc = {126}, timestamp = {2008.08.31}, url = {http://www.nature.com/nature/journal/v421/n6918/abs/nature01336.html}, ut = {ISI:000180165500032} } @ARTICLE{Gulde2001, author = {Gulde, S. and Rotter, D. and Barton, P. and Schmidt-Kaler, F. and Blatt, R. and Hogervorst, W.}, title = {Simple and efficient photo-ionization loading of ions for precision ion-trapping experiments}, journal = {Applied Physics B-Lasers And Optics}, year = {2001}, volume = {73}, pages = {861--863}, number = {8}, month = dec, owner = {herskind}, sn = {0946-2171}, timestamp = {2008.06.06}, url = {http://www.springerlink.com/content/w30wqwahxlp1jw1l/}, ut = {ISI:000173171800016} } @ARTICLE{Guthohrlein2001, author = {Guthohrlein, G.

At present, photons are the best carriers of quantum information between physically separated sites(11,12) and quantum-information processing using stationary qubits(10) is most promising, with the furthest advances having been made with trapped ions(13-15). The implementation of complex quantum-information-processing networks(11,12) hence requires devices to efficiently couple photons and stationary qubits. Here, we present the first CQED experiments demonstrating that the collective strong-coupling regime(2) can be reached in the interaction between a solid in the form of an ion Coulomb crystal(16) and an optical field. The obtained coherence times are in the millisecond range and indicate that Coulomb crystals positioned inside optical cavities are promising for realizing a variety of quantum-information devices, including quantum repeaters(12) and quantum memories for light(17,18). Moreover, cavity optomechanics(19) using Coulomb crystals might enable the exploration of similar phenomena investigated using more traditional solids, such as micro- mechanical oscillators(20).}, af = {Herskind, Peter F.EOLEOLDantan, AurelienEOLEOLMarler, Joan P.EOLEOLAlbert, MagnusEOLEOLDrewsen, Michael}, c1 = {[Herskind, Peter F.; Dantan, Aurelien; Marler, Joan P.; Albert, Magnus; Drewsen, Michael] Univ Aarhus, QUANTOP, Danish Natl Res Fdn, Ctr Quantum Opt,Dept Phys & Astron, DK-8000 Aarhus C, Denmark.}, di = {10.1038/NPHYS1302}, em = {drewsen@phys.au.dk}, fu = {Carlsberg Foundation ; Danish Natural Science Research Council}, fx = {We acknowledge financial support from the Carlsberg Foundation and theEOLEOLDanish Natural Science Research Council through the ESF EuroQUAMEOLEOLproject CMMC.

As a consequence, complete information about the pulse cannot be perfectly recorded in a classical memory, even in principle. In the field of quantum information, this has led to the long-standing challenge of how to achieve a high-fidelity transfer of an independently prepared quantum state of light onto an atomic quantum state(1-4). Here we propose and experimentally demonstrate a protocol for such a quantum memory based on atomic ensembles. Recording of an externally provided quantum state of light onto the atomic quantum memory is achieved with 70 per cent fidelity, significantly higher than the limit for classical recording. Quantum storage of light is achieved in three steps: first, interaction of the input pulse and an entangling field with spin-polarized caesium atoms; second, subsequent measurement of the transmitted light; and third, feedback onto the atoms using a radio-frequency magnetic pulse conditioned on the measurement result. The density of recorded states is 33 per cent higher than the best classical recording of light onto atoms, with a quantum memory lifetime of up to 4 milliseconds.}, c1 = {Univ Copenhagen, Danish Quantum Opt Ctr QUANTOP, Niels Bohr Inst, DK-2100 Copenhagen O, Denmark.EOLEOLAarhus Univ, Danish Quantum Opt Ctr QUANTOP, Dept Phys, DK-8000 Aarhus, Denmark.EOLEOLMax Planck Inst Quantum Opt, D-85748 Garching, Germany.EOLEOLFree Univ Brussels, Ecole Polytech, QUIC, B-1050 Brussels, Belgium.EOLEOLPalacky Univ, Dept Opt, Olomouc 77200, Czech Republic.}, di = {10.1038/nature03064}, em = {polzik@nbi.dk}, ga = {874AA}, j9 = {NATURE}, ji = {Nature}, keywords = {TELEPORTATION; ENTANGLEMENT; STORAGE; PHOTON; STATE; COMMUNICATION}, la = {English}, nr = {22}, owner = {herskind}, pa = {MACMILLAN BUILDING, 4 CRINAN ST, LONDON N1 9XW, ENGLAND}, pg = {5}, pi = {LONDON}, publisher = {Nature Publishing Group}, rp = {Polzik, ES, Univ Copenhagen, Danish Quantum Opt Ctr QUANTOP, Niels BohrEOLEOLInst, DK-2100 Copenhagen O, Denmark.}, sc = {Multidisciplinary Sciences}, sn = {0028-0836}, tc = {165}, timestamp = {2008.08.31}, url = {http://www.nature.com/nature/journal/v432/n7016/abs/nature03064.html}, ut = {ISI:000225322100040} } @ARTICLE{Keller2004, author = {Keller, M. and Lange, B. and Hayasaka, K. and Lange, W. and Walther, H.}, title = {Continuous generation of single photons with controlled waveform in an ion-trap cavity system}, journal = {Nature}, year = {2004}, volume = {431}, pages = {1075--1078}, number = {7012}, month = oct, owner = {herskind}, sn = {0028-0836}, timestamp = {2008.05.20}, url = {http://www.nature.com/nature/journal/v431/n7012/abs/nature02961.html;jsessionid=1E6787C45FB44451CBF4C6309428D954}, ut = {ISI:000224730800034} } @ARTICLE{Keller2003, author = {Keller, M. and Lange, B. and Hayasaka, K. and Lange, W. and Walther, H.}, title = {Deterministic coupling of single ions to an optical cavity}, journal = {Applied Physics B-Lasers And Optics}, year = {2003}, volume = {76}, pages = {125--128}, number = {2}, month = feb, owner = {herskind}, sn = {0946-2171}, timestamp = {2008.05.16}, url = {http://www.springerlink.com/content/m7488lvbhmp87vp2/}, ut = {ISI:000182170800005} } @INBOOK{Kelly1998, pages = {225-289}, title = {Laser Ablation abd Desorption}, publisher = {Academic Press, New York}, year = {1998}, editor = {Miller, J. and Haglund, R.

Although sufficient conditions have been formulated for the physical resources required to achieve quantum computation and communication(2), there is a growing understanding of the power of quantum measurement combined with the conditional evolution of quantum states for accomplishing diverse tasks in quantum information science(3-5). For example, a protocol has recently been developed(6) for the realization of scalable long-distance quantum communication and the distribution of entanglement over quantum networks. Here we report the first enabling step in the realization of this protocol, namely the observation of quantum correlations for photon pairs generated in the collective emission from an atomic ensemble. The nonclassical character of the fields is demonstrated by the violation of an inequality involving their normalized correlation functions.

Dynamical gates have been proposed(1,2) in the context of trapped ions; however, geometric phase gates (which change only the phase of the physical qubits) offer potential practical advantages because they have higher intrinsic resistance to certain small errors and might enable faster gate implementation. Here we demonstrate a universal geometric pi-phase gate between two beryllium ion-qubits, based on coherent displacements induced by an optical dipole force. The displacements depend on the internal atomic states; the motional state of the ions is unimportant provided that they remain in the regime in which the force can be considered constant over the extent of each ion's wave packet. By combining the gate with single-qubit rotations, we have prepared ions in an entangled Bell state with 97% fidelity-about six times better than in a previous experiment(3) demonstrating a universal gate between two ion-qubits. The particular properties of the gate make it attractive for a multiplexed trap architecture(4,5) that would enable scaling to large numbers of ionqubits.}, c1 = {Natl Inst Stand & Technol, Time & Frequency Div, Boulder, CO 80305 USA.EOLEOLUniv Colorado, Dept Phys, Boulder, CO 80309 USA.EOLEOLUniv Oxford, Dept Phys, Oxford OX1 3PU, England.EOLEOLInst Phys, YU-11001 Belgrade, Yugoslavia.}, di = {10.1038/nature01492}, ga = {659WV}, j9 = {NATURE}, ji = {Nature}, keywords = {QUANTUM COMPUTATION; TRAP; STATE; DECOHERENCE; COMPUTER; MOTION}, la = {English}, nr = {22}, owner = {herskind}, pa = {MACMILLAN BUILDING, 4 CRINAN ST, LONDON N1 9XW, ENGLAND}, pg = {4}, pi = {LONDON}, publisher = {Nature Publishing Group}, rp = {Wineland, DJ, Natl Inst Stand & Technol, Time & Frequency Div, 325EOLEOLBroadway, Boulder, CO 80305 USA.}, sc = {Multidisciplinary Sciences}, sn = {0028-0836}, tc = {222}, timestamp = {2008.08.31}, url = {http://www.nature.com/nature/journal/v422/n6930/abs/nature01492.html}, ut = {ISI:000181801200039} } @ARTICLE{Leibfried2005, author = {Leibfried, D. and Knill, E. and Seidelin, S. and Britton, J. and Blakestad, R.

In this Colloquium the author reviews several ideas indicating how such techniques can be used for accurate manipulation of quantum states of atomic ensembles and photons. First a technique is discussed that allows one to transfer quantum states between light fields and metastable states of matter. The technique is based on trapping quantum states of photons in coherently driven atomic media, in which the group velocity is adiabatically reduced to zero. Next, possible mechanisms are outlined for manipulating quantum states of atomic ensembles. Specifically, a "dipole blockade" technique is considered in which optical excitation of mesoscopic samples into Rydberg states can be used to control the state of ensembles at the level of individual quanta. It is also noted that even simple processes involving atom-photon correlations can be used to effectively manipulate the ensemble states. Potentially these techniques can be used for implementation of important concepts from quantum information science.}, c1 = {Harvard Univ, Dept Phys, Cambridge, MA 02138 USA.}, ga = {675VY}, j9 = {REV MOD PHYS}, ji = {Rev.

Large-scale quantum information processors require stable and addressable quantum memories, usually in the form of fixed quantum bits ( qubits), and a means of transferring and entangling the quantum information between memories that may be separated by macroscopic or even geographic distances. Atomic systems are excellent quantum memories, because appropriate internal electronic states can coherently store qubits over very long timescales. Photons, on the other hand, are the natural platform for the distribution of quantum information between remote qubits, given their ability to traverse large distances with little perturbation. Recently, there has been considerable progress in coupling small samples of atomic gases through photonic channels(2,3), including the entanglement between light and atoms(4,5) and the observation of entanglement signatures between remotely located atomic ensembles(6) (-8). In contrast to atomic ensembles, single-atom quantum memories allow the implementation of conditional quantum gates through photonic channels2,9, a key requirement for quantum computing. Along these lines, individual atoms have been coupled to photons in cavities(2,10-12), and trapped atoms have been linked to emitted photons in free space(13-17). Here we demonstrate the entanglement of two fixed single-atom quantum memories separated by one metre. Two remotely located trapped atomic ions each emit a single photon, and the interference and detection of these photons signals the entanglement of the atomic qubits. We characterize the entangled pair by directly measuring qubit correlations with near-perfect detection efficiency. Although this entanglement method is probabilistic, it is still in principle useful for subsequent quantum operations and scalable quantum information applications(18-20).}, af = {Moehring, D.

But this limitation is not fundamental-quantum non-demolition strategies(1-3) permit repeated measurements of physically observable quantities, yielding identical results. For example, quantum non-demolition measurements of light intensity have been demonstrated(4-14), suggesting possibilities for detecting weak forces and gravitational waves(3). But such experiments, based on nonlinear optics, are sensitive only to macroscopic photon fluxes. The non-destructive measurement of a single photon requires an extremely strong matter-radiation coupling; this can be realized in cavity quantum electrodynamics(15), where the strength of the interaction between an atom and a photon can overwhelm all dissipative couplings to the environment. Here we report a cavity quantum electrodynamics experiment in which we detect a single photon non-destructively. We use atomic interferometry to measure the phase shift in an atomic wavefunction, caused by a cycle of photon absorption and emission. Our method amounts to a restricted quantum non-demolition measurement which can be applied only to states containing one or zero photons.

Such planar ion traps are compatible with modern semiconductor fabrication techniques and can be scaled to make compact, many-zone traps. In this paper we present an experimental realization of planar ion traps using electrodes on a printed circuit board to trap linear chains of tens of charged particles of 0.44 mu m diameter in a vacuum of 15 Pa (10(-1) torr). With these traps we address concerns about the low trap depth of planar ion traps and develop control electrode layouts for moving ions between trap zones without facing some of the technical difficulties involved in an atomic ion-trap experiment. Specifically, we use a trap with 36 zones (77 electrodes) arranged in a cross to demonstrate loading from a traditional four-rod linear Paul trap, linear ion movement, splitting and joining of ion chains, and movement of ions through intersections. We further propose an additional dc-biased electrode above the trap which increases the trap depth dramatically, and a planar ion-trap geometry that generates a two-dimensional lattice of point Paul traps.}, c1 = {MIT, Ctr Bits & Atoms, Cambridge, MA 02139 USA.EOLEOLMIT, Dept Phys, Cambridge, MA 02139 USA.}, di = {10.1103/PhysRevA.73.032307}, ga = {028DQ}, j9 = {PHYS REV A}, ji = {Phys.

In practice, however, light forces in the microwave domain are insufficient to support an atom against gravity. Although optical photons can provide forces of the required magnitude, atomic decay rates and cavity losses are larger too, and so the atom-cavity system must be continually excited by an external laser(3,4). Such an approach also permits continuous observation of the atom's position, by monitoring the light transmitted through the cavity(5-9). The dual role of photons in this system distinguishes it from other single-atom experiments such as those using magneto-optical traps(10-12), ion traps(13,14) or a far-off-resonance optical trap(15). Here we report high-finesse optical cavity experiments in which the change in transmission induced by a single slow atom approaching the cavity triggers an external feedback switch which traps the atom in a light field containing about one photon on average. The oscillatory motion of the trapped atom induces oscillations in the transmitted light intensity; we attribute periodic structure in intensity-correlation-function data to 'long-distance' flights of the atom between different anti-nodes of the standing-wave in the cavity. The system should facilitate investigations of the dynamics of single quantum objects and may find future applications in quantum information processing.}, c1 = {Max Planck Inst Quantenopt, D-85748 Garching, Germany.}, ga = {298BG}, j9 = {NATURE}, ji = {Nature}, keywords = {OPTICAL CAVITY; NEUTRAL ATOMS; FIELD; ION}, la = {English}, nr = {25}, owner = {herskind}, pa = {PORTERS SOUTH, 4 CRINAN ST, LONDON N1 9XW, ENGLAND}, pg = {4}, pi = {LONDON}, publisher = {Macmillan Magazines Ltd}, rp = {Rempe, G, Max Planck Inst Quantenopt, Hans Kopfermann Str 1, D-85748EOLEOLGarching, Germany.}, sc = {Multidisciplinary Sciences}, sn = {0028-0836}, tc = {216}, timestamp = {2008.08.31}, url = {http://www.nature.com/nature/journal/v404/n6776/abs/404365a0.html}, ut = {ISI:000086119000042} } @ARTICLE{Pollock1973, author = {Pollock, E.

The Cirac-Zoller proposal(1) for a scalable quantum computer is based on a string of trapped ions whose electronic states represent the quantum bits of information (or qubits). In this scheme, quantum logical gates involving any subset of ions are realized by coupling the ions through their collective quantized motion. The main experimental step towards realizing the scheme is to implement the controlled-NOT (CNOT) gate operation between two individual ions. The CNOT quantum logical gate corresponds to the XOR gate operation of classical logic that flips the state of a target bit conditioned on the state of a control bit. Here we implement a CNOT quantum gate according to the Cirac-Zoller proposal(1). In our experiment, two Ca-40(+) ions are held in a linear Paul trap and are individually addressed using focused laser beams(2); the qubits(3) are represented by superpositions of two long-lived electronic states.

Measurements of ion recooling after cooling is temporarily suspended yield a heating rate of approximately 5 motional quanta per millisecond for a trap frequency of 2.83 MHz, sufficiently low to be useful for QIP.}, c1 = {NIST, Div Time & Frequency, Boulder, CO 80305 USA.}, di = {10.1103/PhysRevLett.96.253003}, em = {seidelin@boulder.nist.gov}, ga = {058XD}, j9 = {PHYS REV LETT}, ji = {Phys.

An ensemble of atoms can store a quantum state in the form of a magnon-which is a quantized collective spin excitation-that can be mapped onto a photon(12-18) with high efficiency(19). Here, we report the phase-coherent transfer of a single magnon from one atomic ensemble to another via an optical resonator serving as a quantum bus that in the ideal case is only virtually populated. Partial transfer deterministically creates an entangled state with one excitation jointly stored in the two ensembles.

Compared with 'chip traps' for confining neutral atoms(5-7), ion traps with similar dimensions and power dissipation offer much higher confinement forces and allow unparalleled control at the single-atom level. Moreover, ion microtraps are of great interest in the development of miniature mass-spectrometer arrays(8), compact atomic clocks(9) and, most notably, large-scale quantum information processors(10,11).
