Breeze is a senior research fellow at UCL working on room-temperature solid-state masers. Research directions: (1) Pentacene maser — first demonstration of a room-temperature, continuous-wave solid-state maser (Science 2018) using photoexcited triplet-state pentacene in p-terphenyl crystal; achieving amplification with noise temperature near 1 K; (2) Diamond NV maser — developing NV-center-based maser for ultra-low-noise microwave amplification at room temperature, relevant to quantum sensing readout chains; (3) Maser applications — quantum-limited amplification for dark matter searches, MRI signal amplification, and quantum communication repeaters; (4) Spin dynamics — understanding triplet-state dynamics in organic crystals for spin polarization control. Strong relevance to quantum-limited microwave sensing.
Antoine Browaeys' group at LCF/IOGS is a world leader in neutral atom quantum simulation using optical tweezer arrays. Research: (1) Rydberg atom tweezer arrays for quantum simulation of strongly correlated many-body systems and quantum sensing; (2) dipole-dipole interactions in Rydberg ensembles; (3) co-founder and key researcher of Pasqal (neutral atom quantum computing company). The group works on scalable neutral atom platforms relevant to quantum sensors and quantum simulation. Open postdoc positions (2026).
Cassidy (formerly Microsoft/Sydney) builds hybrid superconductor-semiconductor quantum devices and the microwave measurement chains needed to read them out: dispersive gate sensing, superconducting resonators coupled to semiconductor nanostructures, and quantum-limited parametric amplification. The programme sits at the boundary between quantum computing hardware and quantum sensing — many of the same circuits used to read a qubit are, viewed differently, near-quantum-limited detectors of microwave photons or of charge. 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 — a superconducting-resonator readout chain with a quantum-limited amplifier is the leading route to inductively-detected spin resonance at sensitivities well below the pT/sqrt(Hz) regime accessible to optical NV ensembles, and Cassidy's group has the full stack of skills required. Mid-career, actively building; good autonomy for a postdoc.
Chaudhuri leads the Princeton Axion Search (PXS) and is a core contributor to the DMRadio program, using solenoidal lumped-element LC resonators, DC-SQUID and near-quantum-limited (traveling-wave parametric amplifier) readout to search for QCD axion dark matter from roughly neV to ueV masses; his group explicitly frames this as electromagnetic quantum sensing beyond the Standard Quantum Limit. He is actively developing superconducting resonators and RF quantum upconverters that push readout sensitivity toward and below the SQL.

Combes is a theorist of continuous quantum measurement, quantum trajectories, quantum-limited amplification and quantum filtering, with a strong record of working directly alongside superconducting-circuit and optical experiments rather than in isolation. Recent directions include the fundamental limits of amplifier-based sensing, error-corrected and adaptive metrology protocols, and characterisation/verification of noisy quantum devices. 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 work supplies the estimation-theoretic scaffolding — quantum Fisher information, back-action limits, adaptive protocols — that determines whether an NV ensemble running DEER or nanoscale NMR at pT/sqrt(Hz) is actually operating at its fundamental bound or leaving sensitivity on the table. Theory PI, but explicitly experiment-facing.
Croot returned from Princeton to found Sydney's Superconducting Quantum Circuits Laboratory. The programme uses superconducting circuits both as quantum processors and as extremely sensitive probes: coupling microwave resonators and qubits to other degrees of freedom (mechanical modes, semiconductor structures, spins) to build hybrid systems, and developing the quantum-limited amplification chain that makes single-microwave-photon detection possible. 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 — superconducting circuits are the principal competitor technology for detecting the weak microwave signals that NV ensembles read magnetically; a quantum-limited or squeezed microwave amplifier is what lets an inductively-detected spin ensemble reach — and beat — the pT/sqrt(Hz) regime. Newly established, well-equipped lab; high autonomy for a postdoc and active recruitment as the lab builds out.
Quantum information theorist with strong focus on quantum sensing.

Works closely with experimental quantum sensing groups at UChicago and beyond.
Kamal directs the QUEST (QUantum Engineering Science and Technology) group, developing theory for quantum-limited readout of superconducting circuits: nonreciprocal parametric (Josephson-junction) amplifiers, left-handed-metamaterial traveling-wave amplifiers, and autonomous entanglement stabilization/error-correction protocols. Her work sets the fundamental noise limits that superconducting-qubit-based quantum sensors and quantum computers can approach, in close collaboration with experimental groups at NIST Boulder and elsewhere. The group is actively recruiting postdoctoral scholars.
