我们提出了一种控制方法，用于在非马尔可夫开放量子系统中选定的量子态之间转移种群。这种传输在单量子位相移操作的辅助下可以生成用于量子计算的通用逻辑门。我们发现，占据概率在不同的环境条件下表现不同，例如温度以及感兴趣的量子系统的频率与欧姆储存器的截止频率之间的比率。我们为量子态工程提供了对非马尔可夫开放量子系统的主动控制。
We propose a control approach to transfer the population between selected quantum states in the non-Markovian open quantum system. This transfers, assisted by single qubit phase shift operations can generate universal logic gates for quantum computing. We find that the occupation probability behaves differently for different environmental conditions, such as the temperature and the ratio between the frequency of the quantum system of interest, and the cut-off frequency of Ohmic reservoir. We provide an active control over non-Markovian open quantum system for the quantum state engineering.
