Optical quantum memory with generalized time-reversible atom-light interactions

S. A. Moiseev, W. Tittel

We examine a quantum memory scheme based on controllable dephasing of atomic coherence of a non-resonant, inhomogeneously broadened Raman transition. We show that it generalizes th…

Quantum memory for light using extended atomic ensembles in a tunable cavity

Alexey Kalachev

Cavity-assisted storage and retrieval of single-photon wave packets in optically thin spatially extended resonant materials are analyzed. It is shown that the use of cavity tuning…

Coherent control of low loss surface polaritons

Ali Kamli, Sergey A. Moiseev, Barry C. Sanders

We propose fast all-optical control of surface polaritons (SPs) by placing an electromagnetically induced transparency (EIT) medium at an interface between two materials. EIT provi…

Evolution of spin entanglement and an entanglement witness in multiple-quantum NMR experiments

E. B. Fel'dman, A. N. Pyrkov

We investigate the evolution of entanglement in multiple-quantum (MQ) NMR experiments in crystals with pairs of close nuclear spins-1/2. The initial thermodynamic equilibrium state…

Backward retrieval in optical quantum memory controlled by an external field

Alexey Kalachev, Stefan Kroll

A scheme for backward retrieval in optical quantum memories in which information is stored in collective states of an extended resonant atomic ensemble is developed such that phase…
