Nonclassical properties of two-mode nonlocal photon- added coherent state

Abstract

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
