APPLICATION OF PAIR COHERENT STATES IN QUANTUM INFORMATION PROCESSES

Rukuan Wu, Shangbin Li, QIN-MEI WANG, Jing‐Bo Xu

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.

QUANTUM TELEPORTATION WITH PAIR-COHERENT STATES

A. Gábris, G. S. Agarwal

Recently it has been argued that all presently performed continuous variable quantum teleportation experiments could be explained using a local hidden variable theory. In this paper we study a modification of the original protocol which requires a fully quantum mechanical explanation even when coherent states are teleported. Our calculations of the fidelity of teleportation using a pair-coherent state under ideal conditions suggests that fidelity above the required limit of 1/2 may be achievable in an experiment also.

Entanglement and Teleportation of Pair Cat States in Amplitude Decoherence Channel

Xu Hang-Shi, Jing‐Bo Xu

The dynamic behavior of the entanglement for the pair cat states in the amplitude decoherence channel is studied by adopting the entanglement of formation determined by the concurrence. Then, we consider the teleportation by using joint measurements of the photon-number sum and phase difference with the pair cat states as an entangle resource and discuss the influence of amplitude decoherence on the mean fidelity of the teleportation.

Improvement quantum teleportation via the pair coherent states

Tran Quang Dat, Truong Minh Duc, Ho Sy Chuong

In this paper, we present two methods to improve the average fidelity in the quantum teleportation processes to teleport a coherent state via the pair coherent states. We use the measuring of the orthogonal quadrature components in the first protocol and the photon number sum and phase difference in the second. The results show that the average fidelity in the first protocol is enhanced by performing a photon number shifting at a receiver, and F av can approach to the unit if q becomes very big. In the second protocol, the average fidelity increases with increasing the amplitude of the pair coherent states. It approaches to the unit in the limit of the big amplitude values of the pair coherent states and small of the input state. The average fidelity of both methods is greatly improved comparing with the Gabris-Agarwal protocol and it approaches to unit depending on the parameters involved.

Entanglement fidelity of coherent-state teleportation with asymmetric quantum channel

Alexei Vladimirovich Chizhov

A strategy for teleporting coherent states with the entanglement fidelity is considered in the general case of an asymmetric teleportation scheme. It is shown that the nonbalanced homodyne detection with the subsequent coherent displacement is required to provide the average teleportation fidelity of entanglement.

Entanglement of Generalized Two-Mode Binomial States and Teleportation

Dongmei Wang, YU You-hong

The entanglement of the generalized two-mode binomial states in the phase damping channel is studied by making use of the relative entropy of the entanglement. It is shown that the factors of q and p play the crucial roles in control the relative entropy of the entanglement. Furthermore, we propose a scheme of teleporting an unknown state via the generalized two-mode binomial states, and calculate the mean fidelity of the scheme.
