Abstract

Quantum teleportation plays a crucial role in quantum information science to date,lots of schemes have been proposed for teleportation.However,in practice,there are many difficulties,such as: the preparation of EPR pairs,the joint Bell measurement,the effects of thermal field and cavity decay.In this(paper),we introduce a single-mode cavity,where the maximally entangled states of atoms 4,5,atoms 6,7,and atoms 8,9 could be prepared,from the form of the effective Hamiltonian.The effects of thermal field and cavity decay are all eliminated.Futhermore,we propose a scheme for teleportation of an unknown tripartite W state in cavity QED.We find that the joint Bell measure is not necessary,and the total success probability can reach 1 in the teleportation process.

Teleportation with Tripartite Entangled State via Thermal Cavity

Zheng‐Yuan Xue, You-Min Yi, Zhuo‐Liang Cao

Teleportation schemes with a tripartite entangled state in cavity QED are investigated. The schemes do not need Bell state measurements and the successful probabilities reach optimality. In addition, the schemes are insensitive to both the cavity decay and the thermal field. We first consider two teleportation schemes via a tripartite GHZ state. The first one is a controlled one for an unknown single-qubit state. The second scheme is teleportation of unknown two-atom entangled state. Then we consider teleporting of single-qubit arbitrary state via a tripartite W state.

EFFICIENT TELEPORTATION OF UNKNOWN ATOMIC ENTANGLED STATES

Yan Zhao, Ming Yang, Zhuo‐Liang Cao

We propose a scheme for teleporting unknown atomic entangled states in cavity QED. With the assistance of a strong classical field, the photon number dependent parts in the effective Hamiltonian are canceled. Thus, the scheme is insensitive to both the cavity decay and the thermal field. In addition, our scheme does not require the Bell-state measurement directly and the success probability can reach 1.0 in our scheme.

Teleportation of A Two-particle Entangled State Via Cavity Quantum Electrodynamics

Hongcai Li

We propose a scheme for the teleportation of an unknown two-particle entangled EPR state without the Bell-state measurement.Alice needs to teleport an unknown two-particle EPR state to Bob.Her atoms and Bob's are prepared in the maximal entangled GHZ state,which forms the quantum channel.She sends two atoms through a single-mode cavity field,and drives them by a strong classical field at the same time.Throngh the interaction between the atoms and the cavity,the states of these atoms are evolved.After the interaction,Alice realizes the teleportation successfully.In the scheme,the effects of thermal field and cavity decay are all eliminated.The success probability is 1.0,and the fidelity is 1.0 too.

We propose a most simple and experimentally feasible scheme for teleporting unknown atomic entangled states in driven cavity quantum electrodynamics (QED). In our scheme, the joint Bell-state measurement (BSM) is not required, and the successful probability can reach 1.0. Furthermore, the scheme is insensitive to the cavity decay and the thermal field.

Tang-Kun Liu

A scheme for the teleportation of an arbitrary two-atom state in driven cavity QED has been proposed.In the teleportation,the maximally two-atom entangled state is required as the quantum channel.The scheme does not require direct Bell-state measurement,but contains Bell-state measurement and is insensitive to the cavity decay and thermal field.Meanwhile,the scheme can also be used to the teleportation of unknown three-atom GHZ state,the probability of the success in the teleportation is 1.0.
