QLA: Quantum Logic Array Microarchitecture, a Brief Overview

Recent experimental advances have demonstrated technologies capable of supporting scalable quantum computation. A critical next step is how to put those technologies together into a scalable, faulttolerant system that is also feasible. We propose a Quantum Logic Array (QLA) microarchitecture that forms the foundation of such a system. QLA is a quantum computer architecture designed for efficient error-correction and error-free communication, regardless of distance. Our designs are validated by analytical reasoning and also by simulation. We emphasize the importance of a datapath oriented large-scale quantum architecture for solving realistic problems, and show how the QLA achieves such design goals. In addition, we introduce ARQ, a tool used to map quantum applications to faulttolerant architectures.
