Continuous variable tripartite entanglement and Einstein-Podolsky-Rosen correlations from triple nonlinearities

Quantum Physics 2009-11-13 v1

Abstract

We compare theoretically the tripartite entanglement available from the use of three concurrent χ(2)\chi^{(2)} nonlinearities and three independent squeezed states mixed on beamsplitters, using the van Loock-Furusawa inequalities. We also define three-mode generalisations of the Einstein-Podolsky-Rosen paradox which are an alternative for demonstrating the inseparability of the density matrix.
