Demonstration of the Einstein-Podolsky-Rosen paradox using nondegenerate parametric amplification

Abstract

We point out in this paper the possibility of demonstrating the Einstein-Podolsky-Rosen paradox via quadrature phase measurements performed on the two output beams of a nondegenerate parametric amplifier. A technique that might be used to demonstrate the paradox has already been partly developed experimentally. © 1989 The American Physical Society.
