K. Tara et Gs. Agarwal, EINSTEIN-PODOLSKY-ROSEN PARADOX FOR CONTINUOUS-VARIABLES USING RADIATION-FIELDS IN THE PAIR-COHERENT STATE, Physical review. A, 50(4), 1994, pp. 2870-2875
We show how the Einstein-Podolsky-Rosen paradox for continuous variabl
es can be tested using the quadrature amplitudes of a radiation field
in the pair-coherent state. Correlated pairs of photons are produced b
y two competing nonlinear processes-four-wave mixing and two-photon ab
sorption.
