Conditions for multipartite continuous-variable entanglement

  • 1. Arbeitsgruppe Quantenoptik, Institut fuer Physik, Universitaet Rostock, D-18051 Rostock (Germany)

Description

Necessary and sufficient observable conditions for the non-negativity of all partial transpositions of multimode quantum states are derived. The result is a hierarchy of inequalities for minors in terms of moments of the given state. The violation of any inequality is a sufficient condition for entanglement. Full entanglement can be certified for a manifold of multimode quantum states. A MATHEMATICA package is given for a systematic test of the hierarchy of conditions
