Disentanglement of Qubit in Dephasing Model
Qing Yang, Yang Ming, Zhuo‐Liang Cao · Communications in Theoretical Physics · 2009
We investigate the entanglement evolution of two qubits that are initially in Werner state under the classical phase noise. We discuss the influence of mixture degree on disentanglement. It is showed that the more mixed the state, the shorter is the time of disentanglement.
