摘要:

传统量子系统控制方法往往面临各类约束,在资源有限的条件下易引发泄漏误差与随机控制误差。强化学习已被证明是完成量子系统控制任务的有效途径。为在资源有限条件下学习得到令人满意的控制策略,本文提出了一种基于增强强化学习的量子系统控制方法(QSC-ERL)。该方法将强化学习中的状态与动作映射为量子系统中的量子态与控制操作,通过采用新型增强神经网络,强化学习可快速实现长期累积奖励最大化,量子态能够从初始态精确演化至目标态。根据候选幺正操作的数量,采用三开关控制进行仿真实验。与其他方法相比,QSC-ERL实现了接近1保真度的量子系统学习控制,且在资源有限条件下完成量子态演化所需的回合数更少。

英文摘要:

Traditional quantum system control methods often face different constraints, and are easy to cause both leakage and stochastic control errors under the condition of limited resources. Reinforcement learning has been proved as an efficient way to complete the quantum system control task. To learn a satisfactory control strategy under the condition of limited resources, a quantum system control method based on enhanced reinforcement learning (QSC-ERL) is proposed. The states and actions in reinforcement learning are mapped to quantum states and control operations in quantum systems. By using new enhanced neural networks, reinforcement learning can quickly achieve the maximization of long-term cumulative rewards, and a quantum state can be evolved accurately from an initial state to a target state. According to the number of candidate unitary operations, the three-switch control is used for simulation experiments. Compared with other methods, the QSC-ERL achieves close to 1 fidelity learning control of quantum systems, and takes fewer episodes to quantum state evolution under the condition of limited resources.
