AI总结:

本文探讨NISQ模拟器在发现新量子动力学现象中的作用,揭示其在多体量子系统研究中的贡献和影响。

摘要:

过去几个世纪的主要技术进步源于我们对非相互作用极限下量子物理的理解。当前的核心挑战是理解复杂量子多体系统的行为,其中相互作用起着关键作用。大约四十年前,理查德·费曼提出利用可控量子系统来高效模拟复杂物理和化学问题,设想了量子或然仪,即高度可调的量子设备,用于模拟尚不理解的量子系统。本文探讨量子模拟器是否已经揭示了新的物理现象——如果有的话,在哪些领域以及产生了什么影响。我们发现,在几个显著的例子中,它们已经加深了我们对多体量子动力学的理解。尽管许多这些见解原则上可以通过理论或数值方法获得,但它们最初是通过量子处理器实现的。虽然仍然有待探索的非平衡动力学问题广阔 landscape 仍在等待探索,但量子模拟器已经开始挑战和修正我们的传统智慧。

英文摘要:

Major technological advances of the past century are rooted in our understanding of quantum physics in the non-interacting limit. A central challenge today is to understand the behavior of complex quantum many-body systems, where interactions play an essential role. About four decades ago, Richard Feynman proposed using controllable quantum systems to efficiently simulate complex physics and chemistry problems, envisioning quantum orreries, highly tunable quantum devices built to emulate less understood quantum systems. Here we ask whether quantum simulators have already uncovered new physical phenomena-and, if so, in which areas and with what impact. We find that, in several notable instances, they have advanced our understanding of many-body quantum dynamics. Although many of these insights could in principle have been obtained theoretically or numerically, they were nevertheless first achieved using quantum processors. While a broad landscape of problems beyond non-equilibrium dynamics still awaits exploration, it is encouraging that quantum simulators are already beginning to challenge and refine our conventional wisdom.
