囚禁离子纠缠态的制备

提出了一种热运动条件下囚禁离子纠缠态制备的方案,离子由不同频率的双色光照射,在这个方案中自由量子振动态只作为中间态,离子间能量的传递是通过耦合离子的振动来完成的,所以方案比较容易在试验中实现.

Preparation of Entangled State for Trappedions

We present an alternative scheme to prepare entangled states of three trapped ions in thermal motion.We simultaneously drive the three ions with two laser beams with diferent frequencies.In this scheme the vibrational degrees of freedom are only regarded as intermediate states and the ions exchange energy via the mediation of the vibration of the vibrational mode in coupling processes.So our scheme might be more simple and feasible.
