Disentanglement of two qubits coupled to an XY spin chain: Role of quantum phase transition

Zi-Gang Yuan, Ping Zhang, Shu-Shen Li

We study the disentanglement of two spin qubits which interact with a general XY spin-chain environment. The dynamical process of the disentanglement is numerically and analyticall…
