我们提出了一个在双模QED腔中产生4比特纠缠相干态的方案。该方案采用了一个单一的二能级原子与腔模色散相互作用，最初准备在相干态。在考虑原子速度扩散和原子效率检测的影响下，得到了态制备的保真度和成功概率。该方案也推广到高阶团簇态。
We propose a scheme to generate a 4-qubit cluster of entangled coherent states in bimodal QED cavities. The scheme employs a single two-level atom that interacts dispersively with cavity modes initially prepared in coherent states. The fidelity and success probability of the state preparation are obtained considering the influence of atomic velocity spread and atomic efficiency detection. The scheme is also generalized for higher order cluster states.
