Entanglement between two macroscopic fields by coherent atom-mediated
exchange of photons
C. L. Garrido Alzar, M. Franca Santos, P. Nussenzveig
abstract: Using two different criteria for continuous variable systems we demonstrated
that pump and probe beams became quantum correlated in a situation of
Electromagnetically Induced Transparency in a sample of Rb atoms. Our result
combines two important features for practical implementations in the field of
quantum information processing. Namely, we proved the existence of entanglement
between two macroscopic light beams, and this entanglement is intrinsically
associated to a strong coherence in an atomic medium.
