The Quantum Separability Problem for Gaussian States
Stefano Mancini, Simone Severini · Electronic Notes in Theoretical Computer Science · 2007
Determining whether a quantum state is separable or entangled is a problem of fundamental importance in quantum information science. This is a brief review in which we consider the problem for states in infinite dimensional Hilbert spaces. We show how the problem becomes tractable for a class of Gaussian states.
