量子反馈控制:如何使用验证定理和粘性解找到最优协议

Quantum Feedback Control: How to use Verification Theorems and Viscosity Solutions to Find Optimal Protocols

Kurt Jacobs, Alireza Shabani

摘要:

虽然反馈控制在量子系统中有许多应用,但为这项任务找到最佳控制协议通常具有挑战性。所谓的“验证定理”和“粘性解”为此提供了两个有用的工具:它们一起给出了一个简单的方法来检查任何给定的协议是否是最优的,并提供了一个数值方法来寻找最优协议。虽然验证定理的处理通常使用复杂的数学语言,但这不是必要的。在这篇文章中,我们给出了一个简单的介绍量子系统中的反馈控制,然后描述验证定理和粘度解决方案在简单的语言。我们还说明了他们的使用与一个具体的例子,目前的利益。

英文摘要:

While feedback control has many applications in quantum systems, finding optimal control protocols for this task is generally challenging. So-called "verification theorems" and "viscosity solutions" provide two useful tools for this purpose: together they give a simple method to check whether any given protocol is optimal, and provide a numerical method for finding optimal protocols. While treatments of verification theorems usually use sophisticated mathematical language, this is not necessary. In this article we give a simple introduction to feedback control in quantum systems, and then describe verification theorems and viscosity solutions in simple language. We also illustrate their use with a concrete example of current interest.
