Abstract

We present a scheme for a direct experimental test of non-separability of a quantum state of two intense optical beams. On this basis, new entanglement-based quantum interferometry schemes using fiber solitons are suggested implying linear or nonlinear coupling of interacting pulses. The prospects of quantum interferometry with fiber solitons for quantum information processing are discusse.
