Bosonic Gaussian channel and Gaussian witness entanglement criterion of continuous variables
Physical Review Research, 2023 We use quantum entanglement witnesses derived from Gaussian operators to study the separable criteria of continuous variable states. For bipartite system, we transform the validity of a Gaussian witness to a bosonic Gaussian channel problem.
