摘要
基于双模纠缠相干态通过光子激发提出一种连续变量的纠缠相干态,即双模激发纠缠相干态。简要介绍了如何通过激光与原子的相互作用来制备双模激发纠缠相干态,并着重研究了双模激发纠缠相干态的保真度,分析了激发光子数对其保真度的影响。
Based on double-mode entangled coherent states resulting from photon excitations, proposes continuous-variable-type entangled coherent states, called double-mode excited entangled coherent states. Introduces briefly the preparation of double-mode excited entangled coherent states by means of interactions of laser and atoms, and focuses on the study of the states fidelity and the influences of photon excitations on the fidelity.
