Journal ArticleDOI
Atom-Light Interactions in Photonic Crystals
Akihisa Goban,Chen-Lung Hung,Su-Peng Yu,J. D. Hood,Juan A. Muniz,Junho Lee,M. J. Martin,Andrew McClung,K. S. Choi,Darrick E. Chang,Oskar Painter,H. J. Kimble +11 more
TL;DR: The development of a novel integrated optical circuit with a photonic crystal capable of both localizing and interfacing atoms with guided photons that is unprecedented in all current atom-photon interfaces is reported.
Journal ArticleDOI
Mapping photonic entanglement into and out of a quantum memory
TL;DR: A protocol where entanglement between two atomic ensembles is created by coherent mapping of an entangled state of light by splitting a single photon and performing subsequent state transfer, which will allow ‘on-demand’Entanglement of atomic en assembles, a powerful resource for quantum information science.
Journal ArticleDOI
Heralded entanglement between atomic ensembles : Preparation, decoherence, and scaling
TL;DR: By way of the concurrence, quantitative characterizations are reported for the scaling behavior of entanglement with excitation probability and for the temporal dynamics of various correlations resulting in the decay of entangling.
Journal ArticleDOI
Demonstration of a state-insensitive, compensated nanofiber trap
Akihisa Goban,K. S. Choi,K. S. Choi,D. J. Alton,Ding Ding,C. Lacroute,M. Pototschnig,Tobias Thiele,Nathaniel P. Stern,H. J. Kimble +9 more
TL;DR: An optical trap is reported that localizes single Cs atoms ≃215 nm from the surface of a dielectric nanofiber by operating at magic wavelengths for pairs of counterpropagating red- and blue-detuned trapping beams, and differential scalar light shifts are eliminated and vector shifts are suppressed.
Journal ArticleDOI
Functional Quantum Nodes for Entanglement Distribution over Scalable Quantum Networks
Chin-Wen Chou,Julien Laurat,Hui Deng,K. S. Choi,Hugues de Riedmatten,Daniel Felinto,H. Jeff Kimble +6 more
TL;DR: The demonstrated quantum nodes and channels can be used as segments of a quantum repeater, providing an essential tool for robust long-distance quantum communication.
