Quantum Optical Memory for Entanglement Distribution
Yisheng Lei, Faezeh Kimiaee Asadi, Tian Zhong +3
Optical photons are powerful carriers of quantum information, which can be delivered in free space by satellites or in fibers on the ground over long distances. Entanglement of qua…
Dephasing of multiparticle Rydberg excitations for fast entanglement generation
F. Bariani, Y. O. Dudin, T. A. B. Kennedy +1
An approach to fast entanglement generation based on Rydberg dephasing of collective excitations (spin-waves) in large, optically thick atomic ensembles is proposed. Long-range $1/…
Entanglement of light-shift compensated atomic spin waves with telecom light
Y. O. Dudin, A. G. Radnaev, R. Zhao +3
Entanglement of a 795 nm light polarization qubit and an atomic Rb spin wave qubit for a storage time of 0.1 s is observed by measuring the violation of Bell's inequality (S = 2.65…
Light storage in a magnetically-dressed optical lattice
Y. O. Dudin, R. Zhao, T. A. B. Kennedy +1
Differential Stark shift compensation for ground state Rb atoms trapped in an elliptically polarized optical lattice and "magic" magnetic field, was recently proposed and de…
Dual species matter qubit entangled with light
S. -Y. Lan, S. D. Jenkins, T. Chaneliere +5
We propose and demonstrate an atomic qubit based on a cold Rb-Rb isotopic mixture, entangled with a frequency-encoded optical qubit. The interface of an atomic qubit…
Multiplexed Memory-Insensitive Quantum Repeaters
O. A. Collins, S. D. Jenkins, A. Kuzmich +1
Long-distance quantum communication via distant pairs of entangled quantum bits (qubits) is the first step towards more secure message transmission and distributed quantum computin…
