Electromagnetically induced transparency in inhomogeneously broadened Lambda-transition with multiple excited levels
O. S. Mishina, M. Scherman, P. Lombardi +7
Electromagnetically induced transparency (EIT) has mainly been modelled for three-level systems. In particular, a considerable interest has been dedicated to the Lambda-configurati…
Atomic-ensemble-based quantum memory for sideband modulations
Jérémie Ortalo, Jean Cviklinski, Pietro Lombardi +4
Interaction of a control and a signal field with an ensemble of three-level atoms allows direct mapping of the quantum state of the signal field into long lived coherences of an at…
Vacuum squeezed light for atomic memories at the D2 cesium line
Sidney Burks, Jérémie Ortalo, Antonino Chiummo +5
We report the experimental generation of squeezed light at 852 nm, locked on the Cesium D2 line. 50% of noise reduction down to 50 kHz has been obtained with a doubly resonant opti…
Reversible Quantum Interface for Tunable Single-sideband Modulation
J. Cviklinski, J. Ortalo, J. Laurat +3
Using Electromagnetically Induced Transparency (EIT) in a Cesium vapor, we demonstrate experimentally that the quantum state of a light beam can be mapped into the long lived Zeema…
Conditionnal squeezing of an atomic alignement
J. Cviklinski, A. Dantan, J. Ortalo +1
We investigate the possibility to perform a Quantum Non Demolition measurement of the collective alignment of an atomic ensemble in the case of a spin. We compare the cas…
