Abstract

We propose a potential scheme to generate a genuine six-atom entangled state [J. Phys. A 42 (2009) 415301] by using atoms in cavity QED system, where the atoms interact simultaneously with the highly detuned single-mode cavity and the strong classical driving field. Thus our approach is insensitive to both the cavity decay and thermal field.

Scheme for Generating a χ-Type Four-Atom Entangled State in Cavity QED

Lin Xiu

We propose a scheme for generating a χ-type four-atom entangled state in cavity QED. In the present scheme, the atoms interact simultaneously with a highly detuned cavity mode with the assistance of a strong classical field. The scheme is insensitive to the cavity decay and the thermal field, which is of importance from the experimental point of view.

Scheme for Implementing Controlled Dense Coding with Six-Atom Cluster State in Cavity QED

Yuanhua Li, Cuicui Li, Xianping Wang +2 more

We propose an experimentally feasible protocol for implementing controlled dense coding with a six-atom cluster state in cavity QED. In the scheme, we investigate that the atoms interact simultaneously with the highly detuned single-mode cavity and the strong classical driving field, and thus our scheme is not sensitive to both the cavity decay and the thermal field. In addition, the four-atom entangled states can be exactly distinguished by performing the single-atom measurements in cavity QED, therefore our scheme might be implemented in a simple way.

Transfer of an Unknown Quantum State Via Cavity QED

Zhiping Huang

A scheme for the distant transfer of a qubit atomic state and atomic entangled states are presented.In the scheme,the identical two-level atoms interact simultaneously with a highly detuned cavity mode and are driven by a strong classical field,and the atomic state evolution is independent of cavity field state.Thus the scheme is insensitive to both the cavity decay and the thermal field and the requirement on the quality factor of the cavity is greatly loosened, which is of importance from the experimental point of view.

Preparation of Genuinely Entangled Six-Atom State via Cavity Quantum Electrodynamics

Wen Zhang, Yimin Liu, Xiaofeng Yin +1 more

A cavity quantum electrodynamics scheme for preparing a genuinely entangled state [A. Borras, et al., J. Phys. A 40 (2007) 13407 ] on six two-level atoms is proposed. In the scheme, the atom-cavity detuning is much bigger than the atom-cavity coupling strength and the necessary preparation time is much shorter than the Rydberg-atom lifespan. Hence the scheme has two distinct features, i.e., insensitive to the cavity decay and the atom radiation.

Deterministic Transfer for an Unknown Atomic Entangled State via Cavity QED

Yan Zhao, Yan-Lin Liao

We present a physics scheme for transferring an unknown atomic entangled state via cavity QED. In the transfer process the interaction between atoms and a single-mode nonresonant cavity with the assistance of a strong classical driving field (substitute) replace the Bell-state measurements. The scheme is insensitive to both the cavity decay and the thermal field. In addition, the success probability can reach 1.0 in our scheme.
