Abstract

An experimentally feasible protocol for realizing dense coding by using a class of W -state in cavity quantum electrodynamics (QED) is proposed in this paper. The prominent advantage of our scheme is that the successful probability of the dense coding with a W -class state can reach 1. In addition, the scheme can be implemented by the present cavity QED techniques.

A SCHEME FOR IMPLEMENTATION OF DENSE CODING WITH W-CLASS STATES IN CAVITY QED

Liu Ye, Juan He

An experimentally feasible scheme for implementing quantum dense coding in cavity QED is proposed. In the scheme a W-class state can first be prepared by letting the atoms interact simultaneously with a highly detuned cavity mode. Then the states coded on this W-class state can be exactly distinguished by detecting atomic states. The scheme is insensitive to the cavity field, and the quantum dense coding can be realized in a simple way.

Scheme for implementing quantum dense coding in cavity QED

Ye Liu, Guang‐Can Guo

An experimentally feasible scheme for implementing quantum dense coding in cavity QED is proposed. In the scheme the atoms interact simultaneously with a highly detuned cavity mode with the assistance of a classical field. The scheme is insensitive to the cavity decay and the thermal field. Bell states can be exactly distinguished via detecting the atomic state, and the quantum dense coding can be realized in a simple way.

We investigate a secure scheme for implementing quantum dense coding via W class state in cavity QED. By collaboration, both of the two receivers could read the sender's secret. In addition, the scheme is an probabilistic and asymmetry one, the receiver who received Alice's qubit has a higher probability of successful cheat compared with the party who have not.

Following a recent proposal ( Phys. Lett. A 346 (2005) 330) about quantum dense coding using a tripartite entangled GHZ state and W state, this paper proposes an experimentally feasible scheme for dense coding in cavity QED by using another peculiar tripartite entangled state. In the scheme the atoms interact simultaneously with a highly detuned cavity mode with the assistance of a classical field, the successful probability of dense coding scheme with this peculiar tripartite entangled state equals 1.

A SCHEME FOR QUANTUM DENSE CODING IN CAVITY QED

Changlin Zou, Zhuo‐Liang Cao

Quantum mechanics allows one to encode the information in the superposition of a quantum state which embodies the nature of quantum nonlocality. Here we propose a realizable physical scheme for a multiparticle quantum dense coding (QDC) between two users in cavity quantum electrodynamics (QED). We also discuss the feasibility of our scheme within current technology.

SCHEME FOR IMPLEMENTING QUANTUM DENSE CODING USING MULTI-ATOM IN CAVITY QED

Ye Liu, Bao‐Long Fang

We propose an experimentally feasible scheme for implementing quantum dense coding in cavity QED. In this scheme, the multi-atoms interact simultaneously with a highly detuned cavity mode, and are driven by a strong classical field. The scheme is insensitive to the cavity decay and the thermal field. Only one interaction between atoms and cavity is required. Multi-atom's GHZ-states can be exactly distinguished via detecting the atomic state, and the quantum dense coding can be realized in a simple way.
