Query: Multicore Quantum Computing   Any architecture for practical quantum computing must be scalable. An
attractive approach is to create multiple cores, computing regions of fixed
size that are well-spaced but interlinked with communication channels. This
exploded architecture can relax the demands associated with a single monolithic
device: the complexity of control, cooling and power infrastructure as well as
the difficulties of cross-talk suppression and near-perfect component yield.
Here we explore interlinked multicore architectures through analytic and
numerical modelling. While elements of our analysis are relevant to diverse
platforms, our focus is on semiconductor electron spin systems in which
numerous cores may exist on a single chip. We model shuttling and
microwave-based interlinks and estimate the achievable fidelities, finding
values that are encouraging but markedly inferior to intra-core operations. We
therefore introduce optimsed entanglement purification to enable high-fidelity
communication, finding that $99.5\%$ is a very realistic goal. We then assess
the prospects for quantum advantage using such devices in the NISQ-era and
beyond: we simulate recently proposed exponentially-powerful error mitigation
schemes in the multicore environment and conclude that these techniques
impressively suppress imperfections in both the inter- and intra-core
operations.
