Quantum telecommunication based on atomic cascade transitions
T. Chaneliere, D. N. Matsukevich, S. D. Jenkins +3
A quantum repeater at telecommunications wavelengths with long-lived atomic memory is proposed, and its critical elements are experimentally demonstrated using a cold atomic ensemb…

Entanglement of a photon and a collective atomic excitation
D. N. Matsukevich, T. Chaneliere, M. Bhattacharya +4
We describe a new experimental approach to probabilistic atom-photon (signal) entanglement. Two qubit states are encoded as orthogonal collective spin excitations of an unpolarized…
