Optimisation of Distributed Quantum Circuits

As quantum computers scale up, their basic components grow farther apart, increasing the challenge of driving accurate interactions between them. Distributed quantum computing proposes a strategy that focuses on separation of concerns: first, engineer a quantum computer that performs reliably on the limited number of qubit it can manage and, then, produce multiple copies of it and connect them together to create larger devices. This strategy establishes two abstract levels of qubit interactions: within a single quantum computing module and between different modules. An efficient quantum circuit would use as few of the latter inter-module qubit interactions as possible, since those will be the main bottleneck of the computation.
