控制开放量子系统：工具、成就与局限
Controlling open quantum systems: Tools, achievements, and limitations
摘要：
利用量子物理学的两个基本要素--相干和纠缠--的量子器件的出现，重新激发了人们对控制开放量子系统的兴趣。成功的实现面临的挑战是在设备操作层面上保留相关的非经典特性。一个主要的障碍是由与环境的相互作用引起的退相干。最优控制理论是一种工具，可以用来确定控制策略的存在退相干。我们在这里回顾最优控制方法的最新进展，允许解决典型的任务，在设备操作的开放量子系统和讨论的例子弛豫优化动力学。最优控制理论也是一个有用的工具，利用控制的环境。我们讨论的例子，并指出未来可能的扩展。
英文摘要：
The advent of quantum devices, which exploit the two essential elements of quantum physics, coherence and entanglement, has sparked renewed interest in the control of open quantum systems. Successful implementations face the challenge to preserve the relevant nonclassical features at the level of device operation. A major obstacle is decoherence which is caused by interaction with the environment. Optimal control theory is a tool that can be used to identify control strategies in the presence of decoherence. We review here recent advances in optimal control methodology that allow for tackling typical tasks in device operation for open quantum systems and discuss examples of relaxation-optimized dynamics. Optimal control theory is also a useful tool to exploit the environment for control. We discuss examples and point out possible future extensions.
