Peter Lodahl's Quantum Photonics Group develops deterministic photon-emitter interfaces using semiconductor quantum dots embedded in photonic nanostructures (nanowires, photonic crystal waveguides). Research targets: single-photon sources with near-unity efficiency and indistinguishability; spin-photon interfaces for quantum repeaters; integrated quantum photonic circuits; and quantum networks based on single emitters. The group leads the Hy-Q Centre for Hybrid Quantum Networks and holds several quantum technology patents and spin-out companies. Borderline case — primarily quantum photonics for networking but with quantum sensing applications (single photon sensing, spin-photon).
Leonardo Midolo develops III-V optoelectronic quantum devices at NBI. Research: (1) nanomechanical quantum photonic integrated circuits (NOEMS) — GaAs waveguide phase shifters, routers, and switches for single-photon routing; (2) heterogeneous integration of quantum dot emitters on silicon and SiN platforms; (3) quantum key distribution with deterministic single-photon sources over field-installed dark fibre. Group established 2022; Beamfox spinout for proximity correction.
