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.

Doherty is a theorist whose early work established much of the modern framework for continuous quantum measurement and quantum feedback control, and who now works across quantum information theory, error correction and the characterisation of quantum devices. For a sensing candidate the relevant body of work is the measurement/feedback theory: conditional evolution under continuous observation, the role of back-action, and the design of feedback protocols that stabilise a quantum system while extracting information from it. 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 — the continuous-measurement formalism he helped build is what one uses to ask whether a pT/sqrt(Hz) NV ensemble measurement is saturating its quantum Fisher information bound or merely its shot-noise bound. Borderline inclusion — the current group output is largely quantum computing theory rather than sensing — but retained under the inclusive rubric given the measurement-theory pedigree.

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.
