Title Quantum information technologies with solid-state spin-photon interfaces
Abstract Single-photon emitters embedded within a solid-state host make natural candidates for quantum information processing nodes, as they combine: strong confinement of light for efficient light-matter coupling, readily controlled electronic spins for fast processing, and long-lived nuclear spins in the host material for memory. Semiconductor quantum dots in III-V materials and colour centers in diamond are among leading candidate platforms. In this talk, I will summarise my team's recent progress on both systems [1-4], and contextualise their future use for quantum communication and computing technologies as part of my new group’s research programme in Oxford.
