论文摘要
在分布式量子计算体系结构,通过量子Internet提供的网络和通信功能,远程量子处理单元(QPU)可以通信和合作,以执行单个NISQ设备无法自行处理的计算任务。为此,分布式量子计算需要新一代的量子编译器,以将任何量子算法映射到任何分布式量子计算体系结构。从本文中,我们首先讨论用于分布式量子计算的编译器设计带来的主要挑战。然后,我们通过分析得出由量子汇编引起的跨越量子计算的上限的上限。基础计算体系结构引起的开销的派生界限以及次优量子编译器引起的额外开销 - 通过论文明确设计,以实现三个关键特征,即通用,通用,有效和有效。最后,我们验证分析结果,并通过广泛的性能分析确认编译器设计的有效性。
In distributed quantum computing architectures, with the network and communications functionalities provided by the Quantum Internet, remote quantum processing units (QPUs) can communicate and cooperate for executing computational tasks that single NISQ devices cannot handle by themselves. To this aim, distributed quantum computing requires a new generation of quantum compilers, for mapping any quantum algorithm to any distributed quantum computing architecture. With this perspective, in this paper, we first discuss the main challenges arising with compiler design for distributed quantum computing. Then, we analytically derive an upper bound of the overhead induced by quantum compilation for distributed quantum computing. The derived bound accounts for the overhead induced by the underlying computing architecture as well as the additional overhead induced by the sub-optimal quantum compiler -- expressly designed through the paper to achieve three key features, namely, general-purpose, efficient and effective. Finally, we validate the analytical results and we confirm the validity of the compiler design through an extensive performance analysis.
