论文摘要
变异量子算法是在嘈杂的中等规模量子（NISQ）技术下实施量子计算的最有前途的系统之一。在各种量子算法中，由参数化的ANSATZ表示的波函数和变异参数通过基于量子计算机的测量输出的经典计算机进行迭代更新。在本文中，我们使用这些算法研究了扰动理论，并前景使用变分量子算法在扰动理论中模拟量子动力学。我们说明了使用算法与详细示例的使用，这些示例与分析计算非常吻合
Variational Quantum Algorithms are among the most promising systems to implement quantum computing under the Noisy-Intermediate Scale Quantum (NISQ) technology. In variational quantum algorithm, wavefunction represented by a parametrized ansatz and variational parameters are updated iteratively with a classical computer based on the measurement outputs from the quantum computer. In this paper, we investigate perturbation theory with these algorithms and prospect the possibility of using the variational quantum algorithm to simulate quantum dynamics in perturbation theory. We illustrate the use of algorithms with detailed examples which are in good agreement with analytical calculations
