    "abstract": "We demonstrate by an explicit model calculation that the decay of\nentanglement of two two-state systems (two qubits) is governed by the product\nof the factors that measure the degree of decoherence of each of the qubits,\nsubject to independent sources of quantum noise. This demonstrates an important\nphysical property that separated open quantum systems can evolve quantum\nmechanically on time scales larger than the times for which they remain\nentangled.",
