Implementation of a Two-Atom (swap) 1/2 Gate in Cavity QED

Abstract

We implement a two-atom (swap) 1/2 gate via cavity QED. During the preparation, a cavity-assisted collision between atoms is required, and this does not need any auxiliary atom. The cavity is only virtually excited, thus our scheme is insensitive to the cavity field states and to the cavity decay. The scheme can be implemented by the present cavity QED techniques.

A SCHEME FOR REALIZATION OF TWO-QUBIT LOGIC GATES IN CAVITY QED

Bao‐Long Fang, Hong-Bo Wan, Ye Liu

We propose a simple scheme for realizing two-qubit logic gate in cavity QED. In our scheme, the quantum controlled-not gate, phase gate and swap gate can be implemented without the ancillary level. The quantum controlled-not gate and phase gate can be realized easily by only one interaction between atoms and a highly detuned cavity mode with the assistance of a strong classical field. Thus, the scheme is insensitive to both the cavity decay and the thermal field.

Realization of Entanglement Swapping in Cavity QED

Jun Li

We propose an entanglement swapping scheme in cavity QED.The different degree entanglement between atoms that never directly interacted can be realized,the unknown entanglement state can be transferred on atoms that never directly interacted.In the scheme,the previously used joint measurement is not needed.Only single measurement on atom is needed in realizing the swapping process.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.

A scheme for realization of quantum SWAP gate in cavity QED

Juan He, Ye Liu, NI Zhi-xiang

A scheme is proposed for the realization of quantum SWAP gate in cavity QED.We consider two three-level atoms simultaneously interact with single-mode cavity in the case of large detuning.Moreover,two classical fields are used to perform the rotations on atoms.The operation and implement course are simple and handy.In addition,during the whole course,the cavity is only virtually excited,thus the decoherence time is greatly prolonged and the demand on the quality factor of the cavity is greatly reduced.Within the present cavity QED techniques,the scheme is realizable.

The realization of entanglement, swap gate and quantum-information transfer for two-atom with cavity QED

Rong Wang, Jin-Yue Gao

We present a scheme to realize entangled states, swap gate and quantum-information transfer for two atoms in cavity QED. The scheme does not require the transfer of quantum information between the atoms and cavity and that the cavity field is only virtually excited, thus the requirement on the quality factor of the cavity is greatly loosened.

Efficient scheme of quantum SWAP gate and multi-atom cluster state via cavity QED

Chunlei Jiang, Mao-Fa Fang, Yao-Hua Hu

In this paper, we propose a physical scheme to realize quantum SWAP gate by using a large-detuned single-mode cavity field and two identical Rydberg atoms. It is shown that the scheme can also be used to create multi-atom cluster state. 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. With the help of our scheme it is very simple to prepare the N -atom cluster state with perfect fidelity and probability. The practical feasibility of this method is also discussed.

Scheme for Quantum Entanglement Swapping on Cavity QED System

Changyong Chen, Yan Yu

We propose a scheme for realizing quantum entanglement swapping between the atoms in cavity QED. With only virtual excitation of the cavity during the interaction between the atoms and cavity, the scheme is insensitive to the cavity mode states and the cavity decay. The ideas can also be utilized for realizing entanglement swapping between the atomic levels in a single atom and the atomic levels in the Bell states and between the atomic levels in the Bell states and the atomic levels in the W states.
