Abstract

We propose a scheme for one-step generation of cluster states with atoms sent through a thermal cavity with strong classical driving field, based on the resonant atom-cavity interaction so that the operating time is sharply short, which is important in the view of decoherence.

Generation of cluster states in thermal cavity

Meifeng Chen, Songshe Ma, Xiaolan Zhang

A scheme is reported for generating a multi-atom cluster state in thermal cavities, which is based on the simultaneous interaction of two two-level atoms with a single-mode cavity field driven by a classical field. The photon-number-dependent parts in the evolution operator are cancelled with the assistant of a strong classical field, so the scheme is insensitive to the thermal field. In the present scheme, the detuning between the atoms and the cavity is equal to the atom-cavity coupling strength, thus the operation speed is greatly improved, which is important in view of decoherence.

Generation of cluster states for cavity fields

Jia Lian-Jun, Zhen‐Biao Yang, Huai‐Zhi Wu +1 more

This paper proposes an alternative scheme for generating cluster-type of entangled coherent states. This scheme is based on resonant interaction of a two-mode cavity with a two-level atom driven by strong classical fields. Thus the required interaction time is greatly shortened, which is very important in view of decoherence.

Generation of cluster states

Ping Dong, Zheng‐Yuan Xue, Ming Yang +1 more

We propose two schemes for the generation of cluster states. One is based on cavity quantum electrodynamics (QED) techniques. The scheme only requires resonant interactions between two atoms and a single-mode cavity. The interaction time is very short, which is important in view of decoherence. Furthermore, we also discuss the cavity decay and atomic spontaneous emission case. The other is based on atomic ensembles. The scheme has an inherent fault tolerance function and is robust to realistic noise and imperfections. All the facilities used in our schemes are well within the current technology.

One-step generation of cluster states in microwave cavity QED

Jun‐Qi Li, Gang Chen, J.-Q. Liang

We propose a potential scheme to generate cluster states with one-step operation based on cavity quantum electrodynamics in a multiatom and microwave cavity system with an additional driven classical field. The proposed quantum operation avoids cavity-field induced decay and may achieve the cluster states with ideal success probability.

Strong-Driving-Assisted Probabilistic State Preparation in Cavity QED

Zhen‐Biao Yang

An alternative scheme is proposed for preparing the superpositions of coherent states with controllable weighting factors along a straight line for a cavity field. The scheme is based on the interaction of a single-mode cavity field with a resonant two-level atom driven by a strong classical field. It is in contrast to the previous methods used in cavity QED of injecting a coherent state into a cavity via a microwave source. In the scheme, the interaction between the cavity mode and atoms is fully resonant, thus the required interaction time is greatly shortened. Moreover, the present scheme requires smaller numbers of operations. In view of decoherence, a reduction of interaction time and numbers of operations for the state preparation is very important for experimental implementation of quantum state engineering.
