摘要:

本文探讨了量子相位估计(QPE)在计算高能激发态中的应用,这些激发态的特征是占据内能壳层的电子的提升。在过去的几十年里,这些状态已经被深入研究,特别是在支持光源的实验努力。与QPE得到的结果进行比较,与各种高精度的多体技术开发来描述核心水平的状态。量子相位估计的可行性,在识别类具有挑战性的动摇状态,其特征在于存在高阶激发效应进行了讨论。

英文摘要:

This paper explores the utility of the quantum phase estimation (QPE) in calculating high-energy excited states characterized by promotions of electrons occupying inner energy shells. These states have been intensively studied over the last few decades especially in supporting the experimental effort at light sources. Results obtained with the QPE are compared with various high-accuracy many-body techniques developed to describe core-level states. The feasibility of the quantum phase estimator in identifying classes of challenging shake-up states characterized by the presence of higher-order excitation effects is also discussed.
