Scheme for Preparation of a Peculiar Type of Tripartite Entangled State via Thermal Cavity

Abstract

We propose a simple scheme for the generation of a peculiar tripartite entangled state via thermal cavity. The peculiar tripartite entangled state shares features of the GHZ and W state simultaneously. The photon-number-dependent parts in the effective Hamiltonian are canceled with the assistance of a strong classical field, thus the scheme is insensitive to both the thermal field and the cavity decay. The only thing one needs to do is to modulate the interaction time only once.

Generation of entangled states in cavity QED

Ye Liu, Long-Bao Yu, Guang‐Can Guo

We propose a scheme to generate four Bell states and a four-atom entangled cluster state in a thermal cavity. The photon-number-dependent parts in the effective Hamiltonian are canceled with the assistance of a strong classical field. The cavity field is only virtually excited; no quantum information will be transferred from the atoms to the cavity and thus the scheme is insensitive to the cavity decay and the thermal field. The scheme can also be used to generate the cluster state for the trapped ions.

我们经由热洞为一个古怪分成三部分的纠缠的状态的产生建议一个简单计划。古怪分成三部分的纠缠的状态同时分享 GHZ 和 W 状态的特征。在有效 Hamiltonian 的 photon-number-dependent 部分与一块强壮的古典地的帮助被取消，这样计划对热地和洞腐烂感觉迟钝。一个人需要做的唯一的事情是调制相互作用时间仅仅一次。

Scheme for Implementing Quantum Dense Coding and Teleportation with Tripartite Entangled State in Cavity QED

Jia Chun-Xia, Peng Zhao-Hui

In this paper, we present a peculiar tripartite entangled state that is inequivalent to both the GHZ state and the W state, and then propose to implement efficient quantum information processing such as quantum dense coding and teleportation with this entangled state in cavity QED. In this scheme the atoms interact with a highly detuned cavity field with the assistance of a strong classical driven field. It does not require the transfer of quantum information between the atomic system and the cavity, and then our scheme is insensitive to both the cavity decay and the 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.

Generation of Maximally Entangled States for Many Two-Level Atoms in a Thermal Cavity

Chunlei Jiang, Mao-Fa Fang

We propose a scheme for generating maximally entangled states for two or more two-level atoms in a thermal cavity. The cavity frequency is large-detuned from the atomic transition frequency, so the Hamiltonian can be expressed as an effective form. The photon-number-dependent parts in the effective Hamiltonian are cancelled with the assistance of a strong classical field, thus the scheme is insensitive to both the cavity decay and the thermal field. The scheme can be used to generate multi-atom Bell-state and Greenberger–Horne–Zeiliner (GHZ) state.

Generation of entangled states for many multilevel atoms in a thermal cavity and ions in thermal motion

Shi-Biao Zheng

We propose a scheme for generating entangled states for two or more multilevel atoms in a thermal cavity. The photon-number-dependent parts in the effective Hamiltonian are canceled with the assistance of a strong classical field. Thus the scheme is insensitive to both the cavity decay and the thermal field. The scheme does not require individual addressing of the atoms in the cavity. The scheme can also be used to generate entangled states for many hot multilevel ions.
