Abstract

In this paper, we propose an effective scheme for rapidly implementing \(\pi \) phase gate in a two-distant-atom–cavity system by combining superadiabatic scheme and quantum Zeno dynamics to construct shortcuts to adiabatic passage. As a typical application of the fast phase gates, a creation of N-atom cluster states is put forward. The influence of various decoherence processes such as atomic spontaneous emission and cavity decay on the fidelity is discussed. Numerical simulations show that the scheme is robust against decoherence caused by atomic spontaneous emission and cavity decay. In this work, superadiabatic shortcuts are used to prepare cluster states for the first time, which is faster than the traditional adiabatic passage technique.

快速实现量子相门和制备簇态的超绝热方案
本文通过结合超绝热方案和量子芝诺动力学来构建绝热通道的捷径,提出了一种在双间距原子腔系统中快速实现(\pi \)相门的有效方案。作为快速相门的典型应用,提出了一种 N 原子簇态的创建。讨论了原子自发辐射和空穴衰变等各种退相干过程对保真度的影响。数值模拟表明,该方案对原子自发辐射和空穴衰变引起的退相干具有很强的抵御能力。在这项工作中,首次使用了超绝热捷径来制备簇态,这比传统的绝热通过技术更快。
