论文摘要
作为量子优势的应用，对动态模拟和量子机学习（QML）的关注很大，而使用QML来增强动态模拟的可能性尚未得到彻底研究。在这里，我们开发了一个框架，用于使用QML方法模拟近期量子硬件上的量子动力学。我们使用概括范围，即机器学习模型在看不见的数据上遇到的错误，以严格分析此框架内算法的训练数据要求。这提供了我们的算法在量子和数据要求方面都具有资源效率的保证。我们的数字表现出有效的问题，并具有问题大小，并且我们模拟了IBMQ-Bogota上的Trotterization的20倍。
Much attention has been paid to dynamical simulation and quantum machine learning (QML) independently as applications for quantum advantage, while the possibility of using QML to enhance dynamical simulations has not been thoroughly investigated. Here we develop a framework for using QML methods to simulate quantum dynamics on near-term quantum hardware. We use generalization bounds, which bound the error a machine learning model makes on unseen data, to rigorously analyze the training data requirements of an algorithm within this framework. This provides a guarantee that our algorithm is resource-efficient, both in terms of qubit and data requirements. Our numerics exhibit efficient scaling with problem size, and we simulate 20 times longer than Trotterization on IBMQ-Bogota.
