论文摘要
变异量子本质量已被提出为低深度量子电路,可用于检查当今嘈杂的中间尺度量子计算机上的密切相关的系统。我们研究了与该算法的单位耦合群集变体的分解形式相关的细节。我们将其应用于具有非平凡行为的简单密切相关的凝结 - 凝结系统 - 一半填充的四个位点哈伯德模型。这项工作表明,在实践中应用该算法时,特别是用于凝结系统的系统时,需要考虑一些细微的问题。
The variational quantum eigensolver has been proposed as a low-depth quantum circuit that can be employed to examine strongly correlated systems on today's noisy intermediate-scale quantum computers. We examine details associated with the factorized form of the unitary coupled-cluster variant of this algorithm. We apply it to a simple strongly correlated condensed-matter system with nontrivial behavior---the four-site Hubbard model at half filling. This work show some of the subtle issues one needs to take into account when applying this algorithm in practice, especially to condensed-matter systems.
