    "abstract": "When a composite quantum state interacts with its surroundings, both quantum\ncoherence of individual particles and quantum entanglement will decay. We have\nshown that under vacuum noise, i.e., during spontaneous emission, two-qubit\nentanglement may terminate abruptly in a finite time [T. Yu and J. H. Eberly,\n\\prl {93}, 140404 (2004)], a phenomenon termed entanglement sudden death (ESD).\nAn open issue is the behavior of mixed-state entanglement under the influence\nof classical noise. In this paper we investigate entanglement sudden death as\nit arises from the influence of classical phase noise on two qubits that are\ninitially entangled but have no further mutual interaction.",
