囚禁离子系统复杂图态的制备

Preparation of complex graph states with ion-trap setup

我们提出一个离子阱系统中产生图态的简单方法。在此方案中,我们只需执行一步操作就可以把许多处在热振动的囚禁离子制备在图态上。另外,我们的方法不须要对离子进行个别定位和激发。

We present a simple scheme to create graph states in an ion-trap system. In the scheme, many ions can be prepared in a complex graph state by one step even in thermal motion. Moreover, our scheme doesn＇t require individual addressing of the ions.
