Violation of Bell inequality and entanglement of decaying Werner states
arXiv:quant-ph/0402023 · doi:10.1016/j.physleta.2004.05.001
Abstract
Bell-inequality violation and entanglement, measured by Wootters' concurrence and negativity, of two qubits initially in Werner or Werner-like states coupled to thermal reservoirs are analyzed within the master equation approach. It is shown how this simple decoherence process leads to generation of states manifesting the relativity of two-qubit entanglement measures.
