论文摘要
我们报告了使用量子退火器计算量子多体系统中相对论效应的第一个结果。使用D-Wave Advantage硬件上的量子Eigensolver（QAE）算法，已经实现了硼样离子在实验方面的良好结构分裂中的平均准确度。我们在许多电子狄拉克理论的框架中获得这些结果。我们通过量子退火工作流程实施QAE，其中包括一种新颖的量子编码方案和基于扰动理论的分解策略。
We report the first results for the computation of relativistic effects in quantum many-body systems using quantum annealers. An average accuracy of 98.9% in the fine structure splitting of boron-like ions with respect to experiments has been achieved using the Quantum Annealer Eigensolver (QAE) algorithm on the D-Wave Advantage hardware. We obtain these results in the framework of the many-electron Dirac theory. We implement QAE through our quantum annealing workflow that includes a novel qubit encoding scheme and a perturbation theory-based decomposition strategy.
