Generation of narrowband twin beams for atomic manipulation

Vincent Boyer, Colin F. McCormick, E. Arimondo +2 more

We have demonstrated 3dB relative intensity squeezing from a non-degenerate four-wave mixing scheme in hot atomic rubidium vapor. The generated twin beams are narrowband and are suitable for atomic manipulation.

Realization of a twin beam source based on four-wave mixing in Cesium

Guillaume Adenier, Davide Calonico, Salvatore Micalizio +3 more

Four-wave mixing (4WM) is a known source of intense non-classical twin beams. It can be generated when an intense laser beam (the pump) and a weak laser beam (the seed) overlap in a [Formula: see text] medium (here Cesium vapor), with frequencies close to resonance with atomic transitions. The twin beams generated by 4WM have frequencies naturally close to atomic transitions, and can be intense (gain [Formula: see text]) even in the CW pump regime, which is not the case for PDC [Formula: see text] phenomenon in nonlinear crystals. So, 4WM is well suited for atom-light interaction and atom-based quantum-protocols. Here, we present the first realization of a source of 4-wave mixing exploiting [Formula: see text] line of Cesium atoms.

Quantum correlated twin atomic beams via photodissociation of a molecular Bose-Einstein condensate

Karen V. Kheruntsyan, P. D. Drummond

We study the process of photodissociation of a molecular Bose-Einstein condensate as a potential source of strongly correlated twin atomic beams. We show that the two beams can possess nearly perfect quantum squeezing in their relative numbers.
