Résumé |
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.
