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.
Choi builds large-scale, individually addressable arrays of solid-state spin qubits (NV centers and related defects) and entangles ancilla nuclear/electronic spins to demonstrate high-precision, entanglement-enhanced quantum sensing, extending the ensemble NV magnetometry regime (DEER/T1 protocols at pT/√Hz) toward single- and few-spin sensors with quantum-error-corrected readout.
Dzurak leads the silicon CMOS quantum dot spin qubit programme at UNSW and co-founded Diraq, the company commercialising it. The group demonstrated the first silicon MOS qubit, two-qubit logic in silicon, and has pushed toward fidelities above the fault-tolerance threshold in industrially-manufactured CMOS devices, including work on gate-stack engineering for low charge noise and on single-electron-transistor charge sensing for readout. 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 relevant transferable asset is the readout: the single-electron-transistor and gate-based dispersive sensors this group builds are among the most sensitive electrometers in existence, the charge-domain analogue of pT/sqrt(Hz) magnetometry. Caveat against the stated preference: the programme is now heavily fabrication- and yield-driven and closely tied to a commercial roadmap, so a sensing-focused postdoc would be somewhat off the group's main axis.
Hamilton heads the Quantum Electronic Devices group and is Deputy Director of the ARC Centre for Future Low Energy Electronics (FLEET). The group works on hole-based quantum devices in GaAs and germanium, where strong spin-orbit coupling allows all-electrical spin control, and on topological materials and one-dimensional transport. The measurements are millikelvin transport and noise spectroscopy of very small signals in mesoscopic 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 — the link is indirect — this is charge/spin transport rather than magnetometry — but the group's expertise in low-noise cryogenic measurement and in spin-orbit-mediated electrical spin control is directly transferable to electrically-detected spin sensing, which is the main alternative to the optical readout that limits pT/sqrt(Hz) NV ensembles. Borderline inclusion; kept under the inclusive rubric.
Studies optical quantum science in solid-state systems with emphasis on photonic integration. Directions: (1) photonic integration of NV-center spin qubits in diamond nanophotonic circuits for scalable quantum sensing arrays; (2) 2D semiconductor (TMD) nanophotonic devices exploiting valley and spin-valley degrees of freedom; (3) engineering light-matter interactions for quantum information and sensing in nanoscale optical cavities. Key goal: scalable on-chip quantum sensing platforms.
Imamoglu leads the Quantum Photonics Group at ETH, working at the intersection of quantum optics and condensed matter physics. Research directions: (1) Quantum emitters in 2D semiconductors — TMD monolayers (MoSe2, WSe2) host localized excitons that act as single-photon emitters; electrically tunable quantum dots in TMD heterostructures with high purity and spin-photon entanglement; developing them as quantum sensors of local electronic correlations at nanometer scales; (2) Strongly correlated electron physics — Mott insulator / Wigner crystal phases in moiré TMD bilayers probed optically with single-photon resolution; mapping electronic phases with nanometer spatial resolution; (3) Polariton quantum fluids — exciton-polaritons in 2D semiconductor microcavities; (4) Quantum nonlinear optics — photon-photon interactions via giant Kerr nonlinearities in strongly coupled quantum dots. Quantum sensing angle: quantum emitters as nanoscale probes of correlated phases.
Jamieson's group built the counted single-ion implantation capability that underpins every donor spin qubit made at UNSW and Melbourne: individual P, Sb or Bi ions are implanted into silicon through a nanoscale aperture while on-chip detector electrodes register the electron-hole pairs from each ion stop event, so the number and position of dopants is known rather than assumed. Recent directions extend this to high-atomic-number donors for nuclear-spin qudits, to colour-centre creation in diamond and silicon carbide by counted implantation, and to characterising the damage and charge environment those ions leave behind. The work is fabrication-forward but its scientific content is single-particle detection metrology. 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 contribution is upstream: the deterministic creation and validation of the very spin defects whose ensembles are later interrogated by DEER and nanoscale NMR at pT/sqrt(Hz).
Laucht works on the quantum control of spins across two platforms: donor spin qubits in silicon (with Morello and Dzurak), where he demonstrated electrically-driven single-spin control in a continuous microwave field and pioneered dressed-state protection against decoherence; and, more recently, spin defects in hexagonal boron nitride — a 2D material whose optically addressable spin defects are the most promising candidate for a van der Waals analogue of the NV centre, with the enormous advantage that the sensor can be placed a single atomic layer from the sample. 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 — hBN spin defects are the field's most active attempt to beat the standoff-distance limitation that caps near-surface NV ensemble sensitivity; a candidate with NV ODMR experience would be immediately productive here, running the same pulse sequences on a new defect. Strong fit.
