A Note on the Disentanglement of Gaussian Quantum States by Symplectic Rotations

Published 24 Mar 2020 in quant-ph, math-ph, math.MP, math.OA, and math.SG | (2003.11049v3)

Abstract: We show that every Gaussian mixed quantum state can be disentangled by conjugation with a metaplectic operator associated with a symplectic rotation. The main tools we use are the Werner-Wolf condition on covariance matrices and the symplectic covariance of Weyl quantization.
