Entanglement criteria and nonlocality for multimode continuous-variable systems Academic Article uri icon


  • We demonstrate how to efficiently derive a broad class of inequalities for entanglement detection in multimode continuous variable systems. The separability conditions are established from partial transposition (PT) in combination with several distinct necessary conditions for a quantum physical state, which include previously established inequalities as special cases. Remarkably, our method enables us to support Peres' conjecture to its full generality within the framework of Cavalcanti-Foster-Reid-Drummond multipartite Bell inequality that the nonlocality necessarily implies negative PT entangled states. 2009 The American Physical Society.
