| 摘 要： | 在非线性克尔介质和光场的相互作用基础之上,提出了一个纠缠相干态(包括多模和高模纠缠)的光学实现方案。发现通过适当选择场的初态,相互作用时间和广义贝尔测量,能产生多模和高维纠缠相干态。同时发现当输入模的态为相干态和叠加数态的情况下,非线性克尔相互作用可产生纠缠。

| Abstract: | The authors of this paper propose an optical scheme for the generation of entangled coherent states which include the multi-mode and high-dimensional entangled coherent states. The scheme is based on the interaction of nonlinear Kerr medium and optical fields. The authors find that muliti - mode and high - dimensional entangled coherent states can be generated through proper selections of the fields' initial states, the time of the interaction and the generalized bell measurement. The authors also find that the interaction of nonlinear Kerr media can generate entanglement when the states of input modes are prepared in coherent state and superposed Fock states. |
