用于量子门控制的深度强化学习

Deep Reinforcement Learning for Quantum Gate Control

Zheng An, D. L. Zhou

摘要:

如何高效、高精度地实现多量子比特门是实现通用容错计算的关键。对于一个具有外部可控参数的物理系统,如何控制这些参数的时间依赖性,从而高效、精确地实现目标多比特量子门是一个很大的挑战。在这里,我们构建了一个决斗双深度Q学习神经网络(DDDQN),以找出可控参数的优化时间依赖性,以实现两个典型的量子门:单量子位Hadamard门和双量子位CNOT门。与传统的最优控制方法相比,这种深度强化学习方法在学习过程中不需要任何梯度信息,就能实现高效、精确的闸门控制。这项工作试图为使用深度强化学习技术研究更多的量子控制问题铺平道路。

英文摘要:

How to implement multi-qubit gates efficiently with high precision is essential for realizing universal fault tolerant computing. For a physical system with some external controllable parameters, it is a great challenge to control the time dependence of these parameters to achieve a target multi-qubit gate efficiently and precisely. Here we construct a dueling double deep Q-learning neural network (DDDQN) to find out the optimized time dependence of controllable parameters to implement two typical quantum gates: a single-qubit Hadamard gate and a two-qubit CNOT gate. Compared with traditional optimal control methods, this deep reinforcement learning method can realize efficient and precise gate control without requiring any gradient information during the learning process. This work attempts to pave the way to investigate more quantum control problems with deep reinforcement learning techniques.
