Researchers demonstrate secure information transfer using spatial correlations in quantum entangled beams of light
A hot 85Rb vapor cell is used as the nonlinear medium needed for the FWM process that generates quantum-correlated twin beams, which we refer to as probe and conjugate. The FWM is based on a double-Λ configuration in the D1 line of 85Rb, as shown on the top inset. The pump beam is reflected from
