单态是纠缠于多态量子系统中的一种特殊态,在量子计算中起着重要的作用。本文提出了一个方案来实现Rydberg原子单态的产生,其中一个Rydberg原子被囚禁在一个光学势中,而其他的Rydberg原子被囚禁在相邻的光学势中。此外,结合Rydberg阻断和绝热通过技术,利用一个N维Rydberg原子与一个()-原子单重态的相互作用,可以产生一个N-原子单重态.与以前的方案相比,我们的方案的优点是可以更简单地实现N粒子N能级单态。
A single state is a special state that entangles multi-state quantum systems and plays a significant role in the field of quantum computation. In this paper, we propose a scheme to realize the generation of single states for Rydberg atoms, where one Rydberg atom is trapped in an optical potential and the others are trapped in an adjacent optical potential. Moreover, combining Rydberg blockade and adiabatic-passage technologies, anN-atom singlet state can be generated with the interaction of anN-dimensional Rydberg atom and an ()-atom singlet state. Compared to previous schemes, the advantage of our proposal is that anN-particleN-level singlet state withmay be realized more simply.
