Bright multiplexed source of indistinguishable single photons with tunable GHz-bandwidth at room temperature
Omri Davidson, Ran Finkelstein, Eilon Poem +1
Narrowband single photons that couple well to atomic ensembles could prove essential for future quantum networks, but the efficient generation of such photons remains an outstandin…

Continuous protection of a collective state from inhomogeneous dephasing
Ran Finkelstein, Ohr Lahad, Itsik Cohen +4
We introduce and demonstrate a scheme for eliminating the inhomogeneous dephasing of a collective quantum state. The scheme employs off-resonant fields that continuously dress the…

Recovering the homogeneous absorption of inhomogeneous media
Ohr Lahad, Ran Finkelstein, Omri Davidson +3
The resonant absorption of light by an ensemble of absorbers decreases when the resonance is inhomogeneously broadened, as only a fraction of the ensemble contributes to the absorp…
