论文摘要
如今，量子计算已经达到了工程阶段，并且功能齐全的量子处理器集成了数百个嘈杂的量子。然而，为了完全揭示量子计算的潜力，将量子计算从实验室中并进入业务现实 - 未来的挑战是实质上扩展量子数，达到数量级，超过了数千个（如果不是数百万）的无噪声量子。为此，通过设想多个中度到小的量子处理器通信和合作以执行超过单个处理设备中可用的计算资源的计算任务，在学术和行业社区之间存在广泛的共识，即考虑分布式计算范式作为实现这种扩展的关键解决方案。这项调查的目的是为读者提供有关分布式量子计算带来的主要挑战和开放问题的概述，并从计算机/通信工程的角度轻松访问和指导相关文献以及突出的结果。
Nowadays, quantum computing has reached the engineering phase, with fully-functional quantum processors integrating hundred of noisy qubits available. Yet -- to fully unveil the potential of quantum computing out of the labs and into business reality -- the challenge ahead is to substantially scale the qubit number, reaching orders of magnitude exceeding the thousands (if not millions) of noise-free qubits. To this aim, there exists a broad consensus among both academic and industry communities about considering the distributed computing paradigm as the key solution for achieving such a scaling, by envision multiple moderate-to-small-scale quantum processors communicating and cooperating to execute computational tasks exceeding the computational resources available within a single processing device. The aim of this survey is to provide the reader with an overview about the main challenges and open problems arising with distributed quantum computing, and with an easy access and guide towards the relevant literature and the prominent results from a computer/communications engineering perspective.
