The sudden death of entanglement is investigated for
the non-Markovian dynamic process of a pair of interacting flux qubits
under a thermal bath. The results show that, for initially two-qubit
entangled states, entanglement sudden death (ESD) always
happens in the thermal reservoir, where its appearance
strongly depends on the environment.
In particular, ESD of the qubits occurs more easily for the non-Markovian
process than for the Markovian one. 相似文献
