二模联合增光子相干态的非经典特性

摘要/Abstract

摘要： 理论研究了联合增光子双模相干态的非经典特性。数值计算表明激发数对光场的的交叉关联特性和亚泊松分布效应有明显影响。只有当激发数时，光场的二个模之间才存在关联效应。随着激发数的增大，光场的二模交叉关联效应加强, 交叉反关联效应减弱。另一方面，光场的亚泊松分布效应随着激发数的增大而减小。最后，提出了一个基于囚禁离子的制备联合增光子双模相干态的方案。

Abstract: We investigate theoretically the nonclassical properties of the nonlocal photon-added two-mode coherent state. The results show the excitation number has significant effect on cross correlation effect and subpoisson distribution effect. Only if the excitation number , the cross correlation effect can be observed. With increasing of the excitation number, the cross correlation effect will strengthen but the cross anticorrelation effect will weaken. On the other hand, the subpoisson distribution effect of the light field is decreased with the increase of the excitation number. Finally, we propose a scheme for the preparation of the nonlocal photon-added two-mode coherent state based on trapped ions.

Key words: Quantum optics, cross correlation function, subpoisson distribution effect
