论文摘要
我们为量子系统中的纯状态和子空间制备提出了一种新方法，该方法采用了连续测量过程和开关耗散控制的输出，以提高收敛速度，以及相对于初始条件的鲁棒性。特别是，我们证明了所提出的闭环策略使所需的目标在全球范围内均匀稳定，并且几乎可以肯定地稳定，并且我们表明，它与基于时间和基于州的基于州的开关控制法的比较有利，在初始化错误的情况下，它具有显着改善。
We propose a new method for pure-state and subspace preparation in quantum systems, which employs the output of a continuous measurement process and switching dissipative control to improve convergence speed, as well as robustness with respect to the initial conditions. In particular, we prove that the proposed closed-loop strategy makes the desired target globally asymptotically stable both in mean and almost surely, and we show it compares favorably against a time-based and a state-based switching control law, with significant improvements in the case of faulty initialization.
