论文摘要

我们描述了使用单位耦合群集(UCC)ANSATZ的变量量子本素层(VQE)算法的汇编策略,该算法旨在减少电路深度和门数。这是通过将Pauli指数项分配到相互通勤的集合中来实现的。然后使用Clifford电路对对角线进行对角线,并使用相多项式形式主义合成。与多种分子,量子编码和基集的幼稚合成相比,该策略平均将CX深度降低了75.4%,高达89.9%。

We describe a compilation strategy for Variational Quantum Eigensolver (VQE) algorithms which use the Unitary Coupled Cluster (UCC) ansatz, designed to reduce circuit depth and gate count. This is achieved by partitioning Pauli exponential terms into mutually commuting sets. These sets are then diagonalised using Clifford circuits and synthesised using the phase polynomial formalism. This strategy reduces cx depth by 75.4% on average, and by up to 89.9%, compared to naive synthesis for a variety of molecules, qubit encodings and basis sets.
