QUANTUM COMPUTING ON OPTICAL NETWORKS: THINKING OUTSIDE THE BOX

Synopsis

Devices that harness the surprising properties of quantum systems at scale hold the possibility of revolutionary advances in information technology.  Algorithms for quantum computers can solve problems that are intractable with classical hardware, including prime factorization and chemical simulation for applications in medicine and industry. Prototype quantum computers are increasingly limited by the constraints of monolithic hardware. Distributed computing on modular quantum processors can break these constraints, but the performance of modular, networked quantum technologies will be contingent upon the quality of their light-matter interconnects. Solid-state colour centres offer optically-coupled spin qubit registers as the basis for quantum networks and distributed quantum computing. In this talk I introduce how these elements may be assembled to create an on-chip spin-photon quantum processor that interfaces with optical fibres for distributed computation and long-range communication over the quantum internet.
