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…
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…
Squeezing and entangling nuclear spins in helium 3
Gael Reinaudi, Alice Sinatra, Aurelien Dantan +1
We present a realistic model for transferring the squeezing or the entanglement of optical field modes to the collective ground state nuclear spin of He using metastability exc…
Teleportation of an atomic ensemble quantum state
Aurelien Dantan, Nicolas Treps, Alberto Bramati +1
We propose a protocol to achieve high fidelity quantum state teleportation of a macroscopic atomic ensemble using a pair of quantum-correlated atomic ensembles. We show how to prep…
Polarization squeezing in a four-level system
V. Josse, A. Dantan, A. Bramati +2
We present a theoretical study of an ensemble of X-like 4-level atoms placed in an optical cavity driven by a linearly polarized field. We show that the self-rotation (SR) process…
