摘要：
We consider a theoretical scheme for entanglement transfer between a two-mode squeezed vacuum field and two initially separable atoms through intensity-dependent couplings. We find that the entanglement transfer between the field and the atoms has an exact period for any given squeezing. We also find that the maximum achievable entanglement of the atomic subsystem is a simple increasing function of r. For sufficiently large squeezing parameter r, it is possible for the atoms to be e...

我们通过紧张依赖者政变石楠为在保持的 two-modesqueezed 真空和二个开始可分离的原子之间的纠纷转移考虑一个理论计划。Wefind 纠纷转移在之间成立并且原子为任何东西的一个准确时期付出了压榨。我们也发现原子分系统的最大的可完成的纠纷是 r 的简单增加功能。为足够地大的压榨的参数 r，在半周期的时间点要纠缠进一个贝尔状态，为原子是可能的。
