Abstract

在现在的工作,为 two-qubit 的同时发生的直接测量的一个简单计划纯状态被建议。计划基于套住的离子并且当二个相同纯状态被给时,仅仅需要一个步骤。在我们的建议的震动的模式仅仅几乎激动,鉴于 decoherence,它是重要的。而且,计划基于当前的技术是可行的。

In the present work, a simple scheme for the direct measurement of the concurrence of two-qubit pure states is proposed. The scheme is based on trapped ions and only needs one step when the two identical pure states are given. The vibrational mode in our proposal is only virtually excited, which is important in view of decoherence. Furthermore, the scheme is feasible based on current technologies.
