量子化场与囚禁离子色散相互作用中的纠缠

Entanglement in the dispersive interaction of trapped ions with a quantized field

F. L. Semião, K. Furuya

摘要:

在色散区研究了囚禁离子与腔场之间的模模纠缠。我们展示了如何一个简单的高斯相干态和postselection的初始准备可以用来产生运动的非局部介观态(NLMS)涉及在不同的陷阱中的离子。我们还研究了N阱离子团簇的动态斯塔克位移引起的纠缠。在这种情况下,所有的纠缠都是由于斯塔克位移对离子运动状态的依赖性,表现为每个离子和场之间的交叉克尔相互作用。

英文摘要:

The mode-mode entanglement between trapped ions and cavity fields is investigated in the dispersive regime. We show how a simple initial preparation of Gaussian coherent states and a postselection may be used to generate motional non-local mesoscopic states (NLMS) involving ions in different traps. We also present a study of the entanglement induced by dynamical Stark-shifts considering a cluster of N-trapped ions. In this case, all entanglement is due to the dependence of the Stark-shifts on the ions' state of motion manifested as a cross-Kerr interaction between each ion and the field.
