Feng Shuang, Alexander Pechen, Tak-San Ho, Herschel Rabitz

摘要:

本文探讨了量子动力学的最优控制中的瞬时和连续观测的效用。模拟的过程进行了几个多层次的量子系统的人口转移的目标。最优控制场被证明能够与观测合作或对抗以实现良好的产量,并且观测的性质可以被优化以更有效地控制量子动力学。量子观测也可以打破动力学对称性,以增加量子系统的可控性。观测引起的量子芝诺效应和反芝诺效应是这些过程的关键操作原理。结果表明,量子观测可以成为控制量子动力学的有效工具。

英文摘要:

This paper explores the utility of instantaneous and continuous observations in the optimal control of quantum dynamics. Simulations of the processes are performed on several multilevel quantum systems with the goal of population transfer. Optimal control fields are shown to be capable of cooperating or fighting with observations to achieve a good yield, and the nature of the observations may be optimized to more effectively control the quantum dynamics. Quantum observations also can break dynamical symmetries to increase the controllability of a quantum system. The quantum Zeno and anti-Zeno effects induced by observations are the key operating principles in these processes. The results indicate that quantum observations can be effective tools in the control of quantum dynamics.
