The frequency non-degenerate parametric amplifier as a device to analyse the Einstein-Podolsky-Rosen paradox
L Gilles, P Garcia-Fernandez
In this paper the output quadrature phase correlations of a frequency nondegenerate parametric amplifier characterized by asymmetric losses, analysed in a preceding paper are applied to the discussion of the Einstein-Podolsky-Rosen (EPR) paradox. We use the formalism developed by Caves et al to describe the combined field modes and adopt the dual local oscillator homodyning scheme to construct an inferred Heisenberg uncertainty principle. The noise level required to demonstrate the existence of the EPR paradox is calculated and the sensitivity of the EPR inference on the asymmetry of the cavity mirror partial transmittivities and on the detuning in frequency between the two detected output fields is analysed. Such an analysis therefore provides a generalization of previous results reported by Reid and Drummond.
