Sumner is a founding figure of the UK dark-matter direct-detection programme (ZEPLIN series, now LZ), working on liquid-xenon TPC design, radiopurity and background control for rare-event searches.

Tim Taminiau (QuTech team leader, Assoc Prof) develops NV-center quantum registers for sensing and quantum networks. Research: (1) NV-center nuclear spin registers — quantum control of up to 50 coupled 13C nuclear spins; (2) nanoscale NMR sensing — mapping external spin networks with sub-nm resolution; (3) silicon-carbide spin qubits — VSi centres for scalable quantum networks with fast entanglement rates; (4) quantum error correction in multi-spin diamond registers. NWO Vici Grant 2026. Quadrupolar nuclear spin spectroscopy of individual nuclei (Nano Letters 2024). Key for sensing proteins at nanoscale.

Tan leads the Superconducting Quantum Detectors group, holding ERC Starting and Consolidator Grants. Two main research pillars: (1) Quantum-limited SIS mixer development — pushing THz SIS heterodyne receivers above the Nb gap (~700 GHz) using NbTiN/NbN films for next-generation ALMA wideband sensitivity upgrade (Band 9) and large-format focal-plane mixer arrays for JCMT/SMA; (2) Superconducting parametric amplifiers (TWPAs) — fabricating kinetic-inductance and Josephson-junction TWPAs achieving near-quantum-limited broadband noise performance from microwave to THz, with applications to dark matter/axion searches (ABRACADABRA/prototype cavity haloscope), quantum computing qubit readout, and CMB-grade receivers. Group is transitioning TWPA fabrication in-house using Beecroft Building cleanroom. ERC Consolidator Grant awarded 2024.

Tan trained at NIST Boulder in the Wineland lineage and brought quantum-logic spectroscopy and entanglement-enhanced metrology to Sydney. His independent programme builds trapped-ion systems for quantum simulation of vibronic and chemical dynamics, for bosonic/qudit encodings, and — most relevant here — for precision measurement that exploits entangled states to beat the standard quantum limit. The group also works on high-fidelity gates and on using motional modes as sensitive transducers of weak forces and electric fields. 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 — entanglement-enhanced protocols are the natural next step beyond the shot-noise-limited pT/sqrt(Hz) ensemble measurements that define the current NV state of the art, and Tan is one of a small number of Australian PIs actually implementing them. Mid-career, actively building; a strong option for a candidate wanting to move from spin ensembles to entangled sensors.

Tarbutt co-leads the Imperial eEDM experiment using YbF molecules and runs an independent molecular array quantum computing/sensing programme. Two parallel eEDM experiments: (1) Ultracold YbF beam — 2D transverse laser cooling producing 200 μK, 2×10^5 molecules/shot, eEDM sensitivity of 1.8×10^−28 e·cm/day (near shot-noise limit); (2) YbF 3D optical lattice — aiming for 10^−30 e·cm/year, requires laser cooling to μK and loading into 3D optical lattice, using novel all-optical spin polarisation and analysis. Also leads UKRI project on testing fundamental physics using arrays of ultracold molecules (CaF in optical tweezers for two-qubit molecular gates). These experiments probe CP-violation and BSM physics at PeV energy scales through precision molecular spectroscopy.

Tesi leads an independent group at Stuttgart's Institute of Physical Chemistry working on optically addressable molecular spin systems -- the effort to reproduce the NV centre's defining trick (optical initialization and readout of a spin) in a designed molecule, where chemistry rather than crystal growth sets the properties. Work spans photogenerated spin-correlated radical pairs, ODMR on molecular chromophore-radical systems, spin-phonon coupling and coherence engineering, and embedding of molecular spins in films and matrices. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is arguably the most direct molecular analogue in the search: the target sensitivity and readout protocols are borrowed straight from NV ensembles, but the emitter is synthetic. Newer, smaller group; good fit for a postdoc who wants to own a direction rather than inherit one.

Thompson leads the Ion Trapping Group at Imperial using RF (Paul) traps with laser-cooled Ca-40 ions and Penning traps. Research foci: (1) High-fidelity quantum logic gates — optimal control techniques for single-ion state manipulation and two-qubit gates; demonstrated >1 s coherence times via Ramsey interferometry in a Penning trap; (2) Precision spectroscopy — ytterbium ion optical clock uncertainty characterisation at 2.2×10^−18 fractional uncertainty (NPL collaboration); proposed precision laser spectrometer for highly charged ions (HCI) in cylindrical Penning traps for QED tests; (3) Axion sensing — collaborating with Devlin on the Penning-trap single-electron photon counter for axion searches; (4) Coulomb crystals — ultrahigh resolution spectroscopy of ion crystals. Past work includes SPECTRAP project at GSI Darmstadt for HCI spectroscopy.

Tilley directs the UNSW Electron Microscope Unit and runs a nanomaterials group whose distinctive capability is in-situ liquid-cell TEM: watching nanoparticle nucleation, growth and catalytic transformation in real time inside the microscope, in liquid, rather than inferring mechanism from before-and-after snapshots. The synthetic side produces magnetic and plasmonic nanoparticles used as biosensor labels and MRI contrast agents, largely in collaboration with Gooding and Reece. 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 group is a supplier and characteriser of the nanoparticle probes that in-cell quantum sensing depends on — including the magnetic-nanoparticle labels whose stray fields a pT/sqrt(Hz) NV sensor would actually detect — and the liquid-cell TEM capability is a rare way to validate what those particles are doing in situ. Borderline inclusion (materials characterisation rather than sensing), kept for the collaborative infrastructure it represents.

Treps leads the Multimode Quantum Optics group at LKB. Research directions: (1) Multimode quantum frequency combs — synchronously pumped OPO (SPOPO) generates entangled networks of squeezed modes with configurable graph structure; first demonstration of quantum frequency comb with multimode squeezing (PRL 2012); (2) Quantum-enhanced multiparameter estimation — quantum Fisher information and multimode squeezing for simultaneous beyond-shot-noise parameter estimation (e.g., frequency comb spectral centroid and energy, PRX 2020); (3) Non-Gaussian quantum states — heralded generation of non-Gaussian cluster states for CV quantum computing; (4) Quantum metrological inequalities — relating non-locality to parameter estimation. Spin-off: Cailabs (multimode fiber light-shaping for telecom and industrial lasers). Co-director of QICS. ERC-funded.

Nicolas Treps' multimode quantum optics group (with Valentina Parigi and Claude Fabre) generates and characterises highly multimode squeezed and entangled states of light. Research: (1) optical frequency combs as multimode squeezed state resources — quantum metrology and sensing with frequency combs; (2) reconfigurable multimode squeezed state networks for quantum computing and sensing; (3) spatiotemporal squeezing with optical parametric amplifiers. Key for quantum-enhanced sensing with light.
