Abstract

We propose a scheme for transfer an unknown atomic state via cavity QED,and use this system to generate four Bell states.The scheme is feasible for current experiment condition.

A scheme for transferring an unknown atomic entangled state via cavity quantum electrodynamics

Wu Tao, Ye Liu, 倪致祥

In this paper, we propose a scheme for transferring an unknown atomic entangled state via cavity quantum electrodynamics (QED). This scheme, which has a successful probability of 100 percent, does not require Bell-state measurement and performing any operations to reconstruct an initial state. Meanwhile, the scheme only involves atom–field interaction with a large detuning and does not require the transfer of quantum information between the atoms and cavity. Thus the scheme is insensitive to the cavity field states and cavity decay. This scheme can also be extended to transferring an entangled state of n-atom.

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.

Scheme for teleportation of an unknown atomic state without the Bell-state measurement

Ye Liu, Guang‐Can Guo

We propose a scheme for teleporting an unknown atomic state in cavity QED. Our scheme does not involve the Bell-state measurement. During the interaction between atom and cavity, the cavity is only virtually excited and thus the scheme is insensitive to the cavity field states and cavity decay. The idea can also be used in the case of teleporting an unknown atomic entangled state.

SECRET SHARING OF N-ATOM ENTANGLED STATE IN CAVITY QED

Zhong‐Xiao Man, Yun‐Jie Xia, Zhanjun Zhang

We propose a scheme to secret sharing of an unknown N-atom entangled state in driven cavity QED. The scheme needs only atomic Bell states as the quantum channels and joint Bell-state measurement is unnecessary. In addition, the scheme is insensitive to the cavity decay and the thermal field.

Transferring a cavity field entangled state in cavity QED

Ye Liu, Guang‐Can Guo

We propose a scheme for transferring an entanglement of zero- and one-photon states from one cavity to another. The scheme, which has 100% success probability, is mainly based on a two-mode cavity dispersively interacting with a three-level atom in the Λ configuration and does not involve Bell-state measurement. This scheme can also be used to teleport an unknown atomic state.

We present a scheme using four two-level atoms and a bimodal cavity to get approximate conditional teleportation of an arbitrary entangled atomic state without using the Bell-state measurement.
