    "abstract": "I investigate the decoherence of two-mode squeezed vacuum states by analyzing\nthe relative entropy of entanglement. I consider two sources of decoherence:\n(i) the phase damping and (ii) the amplitude damping due to the coupling to the\nthermal environment. In particular, I give the exact value of the relative\nentropy of entanglement for the phase damping model. For the amplitude damping\nmodel, I give an upper bound for the relative entropy of entanglement, which\nturns out to be a good approximation for the entanglement measure in usual\nexperimental situations.",
