Quantum light from solid-state emitters: sources, interfaces and measurements.

We investigate the interaction of light and matter at the quantum level. By leveraging the unique properties of quantum materials, we aim to understand quantum phenomena and exploit them in quantum photonic technologies.

POEM (PI) — Polarisation-path correlated single photons from moiré-trapped excitons in WSe₂/MoSe₂ heterobilayers, controlled by electrical doping and a dichromatic two-laser excitation scheme.

ECO-Q (co-PI, with L. Viña) — Spin-momentum locking in the edge states of honeycomb polariton lattices, and spin-controlled lasing of counter-propagating edge modes — routing light with polarisation alone.

COMPHORT (Coordinator) — hBN emitters in tunable open microcavities and LED-driven excitation for free-space QKD. Partners: Univ. Oldenburg, TU Berlin, İzmir IoT, Univ. Bristol, nanoplus and QLocked. Project website.
