Lauret studies quantum light from low-dimensional materials - room-temperature single-photon emission from carbon nanotubes and defects in hexagonal boron nitride, coupled to photonic/plasmonic structures - a fundamental-photon and quantum-emitter platform. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides solid-state single-photon sources adjacent to spin-defect sensing.

Mulvaney directs the ARC Centre of Excellence in Exciton Science and runs Melbourne's nanoscience laboratory. The group's distinctive capability is single-particle and single-emitter optical spectroscopy: photon-antibunching and blinking statistics from individual quantum dots and perovskite nanocrystals, photothermal and dark-field spectroscopy of individual metal nanoparticles, and the electrochemical control of single-nanocrystal charge state. Applications run from LEDs and solar cells to quantum-dot probes for single-particle tracking in cells. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his single-emitter photon-statistics measurements share the shot-noise-limited photon-counting methodology of NV-ensemble ODMR readout, and the group's nanocrystal probes are direct competitors/complements to nanodiamond in cellular sensing. Large, well-resourced group.

Utzat studies the quantum optical properties of single colloidal quantum dots and perovskite nanocrystals, using photon-correlation spectroscopy to characterize and improve their performance as solid-state single-photon sources for quantum photonic applications. The group is actively recruiting postdocs.
