利用暗态制备离子Cluster State

Preparing Cluster States Via Adiabatic Evolution

提出一种利用暗态制备Cluster state的方案.该方案的主要优点是不需要离子的振荡模来存储信息,量子信息存储于多能级离子的基态中;并且整个制备过程中,系统始终处于暗态中,有效地抑制了环境对系统的消相干和实验参数不稳定等因素的影响.在当前的实验技术条件下,该方案是可行的.

A scheme for the implementation of cluster states via adiabatic evolution is proposed. In the scheme ,the quantum information is stored in the ground states of the multiple-level ions instead of the vibrational mode. Moreover, the decoherence and the instability of the parameter of the experiment are suppressed during the whole procedure since the system is always in the dark states. The present scheme is feasible based on current technolo- gies.
