摘要

格子 QCD 的终极任务之一是根据强相互作用的第一原理模拟原子核。这对目前的计算技术来说是一项极其艰巨的任务，但在即将到来的量子计算时代或许可以实现。在本文中，我们讨论了晶格 QCD 的经典模拟和量子模拟的计算复杂性。结果表明，量子模拟在核子数的函数上具有更好的扩展性，因此在大型原子核上会有更好的表现。

Toward nuclear physics from lattice QCD on quantum computers

One of the ultimate missions of lattice QCD is to simulate atomic nuclei from the first principle of the strong interaction. This is an extremely hard task for the current computational technology, but might be reachable in coming quantum computing era. In this paper, we discuss the computational complexities of classical and quantum simulations of lattice QCD. It is shown that the quantum simulation scales better as a function of a nucleon number and thus will outperform for large nuclei.

期刊介绍： Progress of Theoretical and Experimental Physics (PTEP) is an international journal that publishes articles on theoretical and experimental physics. PTEP is a fully open access, online-only journal published by the Physical Society of Japan. PTEP is the successor to Progress of Theoretical Physics (PTP), which terminated in December 2012 and merged into PTEP in January 2013. PTP was founded in 1946 by Hideki Yukawa, the first Japanese Nobel Laureate. PTEP, the successor journal to PTP, has a broader scope than that of PTP covering both theoretical and experimental physics. PTEP mainly covers areas including particles and fields, nuclear physics, astrophysics and cosmology, beam physics and instrumentation, and general and mathematical physics.
