Decoherence measurement of single phonons using spectral interference
F. C. Waldermann, B. J. Sussman, J. Nunn +9
A technique to measure the decoherence time of optical phonons in a solid is presented. Phonons are excited with a pair of time delayed 80 fs, near infrared pulses via spontaneous,…
Creating diamond color centers for quantum optical applications
F. C. Waldermann, P. Olivero, J. Nunn +10
Nitrogen vacancy (NV) centers in diamond have distinct promise as solid-state qubits. This is because of their large dipole moment, convenient level structure and very long room-te…
Efficient spatially-resolved multimode quantum memory
K. Surmacz, J. Nunn, F. C. Waldermann +4
We propose a method that enables efficient storage and retrieval of a photonic excitation stored in an ensemble quantum memory consisting of Lambda-type absorbers with non-zero Sto…
Mapping broadband single-photon wavepackets into an atomic memory
J. Nunn, I. A. Walmsley, M. G. Raymer +4
We analyze a quantum optical memory based on the off-resonant Raman interaction of a single broadband photon, copropagating with a classical control pulse, with an atomic ensemble.…
Entanglement fidelity of quantum memories
K. Surmacz, J. Nunn, F. C. Waldermann +3
We introduce a figure of merit for a quantum memory which measures the preservation of entanglement between a qubit stored in and retrieved from the memory and an auxiliary qubit.…
Modematching an optical quantum memory
J Nunn, I A Walmsley, M G Raymer +4
We analyse the off-resonant Raman interaction of a single broadband photon, copropagating with a classical `control' pulse, with an atomic ensemble. It is shown that the classical…
