Abstract

We investigate the entanglement of pair coherent states in the phase damping channel by adopting the relative entropy of entanglement and propose a protocol of teleportation via pair coherent states. The fidelity of the protocol is then analyzed and the influence of phase damping on the teleportation fidelity examined.
