摘要:

我们提出了一个经典的控制机制,量子设备使用强化学习。我们的策略被应用到量子近似优化算法(QAOA),以优化的目标函数,编码的解决方案,一个硬的组合问题。该方法提供了量子设备的最佳控制,随后将QAOA重新表述为一个环境,在该环境中,自主经典代理进行交互并执行操作以获得更高的奖励。该公式允许混合经典-量子设备使用深度Q学习的连续公式根据先前的执行来训练自身,以控制QAOA的连续自由度。我们的方法选择性地使用量子测量来完成对代理可用的量子态的观察。我们运行的MAXCUT实例的大小N = 21获得最佳的结果,这种方法的测试。我们展示了如何使用这种提法来转移知识,从较短的培训插曲,以达到更长的执行QAOA提供更高的结果的制度。

英文摘要:

We present a classical control mechanism for Quantum devices using Reinforcement Learning. Our strategy is applied to the Quantum Approximate Optimization Algorithm (QAOA) in order to optimize an objective function that encodes a solution to a hard combinatorial problem. This method provides optimal control of the Quantum device following a reformulation of QAOA as an environment where an autonomous classical agent interacts and performs actions to achieve higher rewards. This formulation allows a hybrid classical-Quantum device to train itself from previous executions using a continuous formulation of deep Q-learning to control the continuous degrees of freedom of QAOA. Our approach makes a selective use of Quantum measurements to complete the observations of the Quantum state available to the agent. We run tests of this approach on MAXCUT instances of size up to N = 21 obtaining optimal results. We show how this formulation can be used to transfer the knowledge from shorter training episodes to reach a regime of longer executions where QAOA delivers higher results.
