Continuous variable tripartite entanglement and Einstein-Podolsky-Rosen correlations from triple nonlinearities
M. K. Olsen, A. S. Bradley, M. D. Reid
Abstract
We compare theoretically the tripartite entanglement available from the use of three concurrent χ(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.
