| Abstract: | We investigate the entanglement of pair cat states in the phase damping channel by adopting the log-negativity and then study the possible violations of Bell's inequalities for the pair cat states in terms of the Wignerrepresentation in phase space based upon parity measurement anddisplacement operation. |
