现在，在各种物理环境中，对单个量子系统的控制已成为现实。反馈控制是一类重要的控制方法，因为它能够减少噪声的影响。在这篇评论中，我们给出了一个介绍性的概述，在量子系统中，反馈可以实现的各种方式，目前用于治疗它的理论方法，它已被证明到目前为止的实验，以及它的应用。在过去的几年里，在实现介观系统的量子测量和控制的能力方面有了快速的实验进展。我们预计，在未来几年将看到进一步的快速进步，在实验室中实现的反馈控制协议的精度和复杂性。
The control of individual quantum systems is now a reality in a variety of physical settings. Feedback control is an important class of control methods because of its ability to reduce the effects of noise. In this review we give an introductory overview of the various ways in which feedback may be implemented in quantum systems, the theoretical methods that are currently used to treat it, the experiments in which it has been demonstrated to date, and its applications. In the last few years there has been rapid experimental progress in the ability to realize quantum measurement and control of mesoscopic systems. We expect that the next few years will see further rapid advances in the precision and sophistication of feedback control protocols realized in the laboratory.
