Storage and recall of weak coherent optical pulses with an efficiency of 25%
M. Sabooni, F. Beaudoin, A. Walther +4
We demonstrate experimentally a quantum memory scheme for the storage of weak coherent light pulses in an inhomogeneously broadened optical transition in a Pr^{3+}: YSO crystal at…
Towards an eficient atomic frequency comb quantum memory
A. Amari, A. Walther, M. Sabooni +8
We present an efficient photon-echo experiment based on atomic frequency combs [Phys. Rev. A 79, 052329 (2009)]. Echoes containing an energy of up to 35% of that of the input pulse…
Demonstration of atomic frequency comb memory for light with spin-wave storage
Mikael Afzelius, Imam Usmani, Atia Amari +8
We present a light-storage experiment in a praseodymium-doped crystal where the light is mapped onto an inhomogeneously broadened optical transition shaped into an atomic frequency…
Experimental superradiance and slow light effects for quantum memories
Andreas Walther, Atia Amari, Stefan Kröll +1
The effects of high optical depth phenomena, such as superradiance, are investigated in potential quantum memory materials. The results may have relevance for several schemes, incl…
