化学量子模拟算法的统一观点

Unified views of quantum simulation algorithms for chemistry

James Daniel Whitfield

摘要:

量子系统的时间演化在物理学、化学以及最近的计算机科学中都很有意义。量子计算机被认为是一种比普通数值方法更有效地传播量子系统的途径。在过去的几年里,研究人员一直在积极地改进量子模拟算法,特别是二次量子化的算法。这项工作继续推进国家的最先进的统一在一个共同的框架下的几个不同的方法。特别是,它突出了第一和第二量化算法的相似性和差异,通常以不同的方式呈现。通过结合这两种方法的方面,这项工作走向一个在线的第二量化算法内操作的单福克空间。本文还统一了主机的算法量子测量的方法,通过消除表面的差异。这项工作的目的不仅是为了给量子模拟一个高层次的理解,但走向实验可实现的算法与化学和超越的实际应用。

英文摘要:

Time evolution of quantum systems is of interest in physics, in chemistry, and, more recently, in computer science. Quantum computers are suggested as one route to propagating quantum systems far more efficiently than ordinary numerical methods. In the past few years, researchers have actively been improving quantum simulation algorithms, especially those in second quantization. This work continues to advance the state-of-the-art by unifying several diverging approaches under a common framework. In particular, it highlights the similarities and differences of the first and second quantized algorithms which are usually presented in a distinct fashion. By combining aspects of the two approaches, this work moves towards an online second quantized algorithm operating within a single-Fock space. This paper also unifies a host of approaches to algorithmic quantum measurement by removing superficial differences. The aim of the effort is not only to give a high-level understanding of quantum simulation, but to move towards experimentally realizable algorithms with practical applications in chemistry and beyond.
