Atatüre leads the ~30-person QOMS group at the Cavendish. Three main thrusts: (1) Spin-based quantum networks — demonstrating distant entanglement generation and photonic cluster states using semiconductor quantum dots (InGaAs, GaAs) and diamond spin defects (NV, SiV, SnV), including a many-body nuclear-spin quantum register demonstrated in 2025 (Nature Physics); (2) Quantum-enhanced nanoscale sensing — scanning NV diamond magnetometry of emergent magnetism in novel 2D/layered materials and quantum transport in nanocircuits, plus nanodiamond-based in-cell sensing (nanoMRI, thermometry, diffusion in C. elegans); (3) Novel quantum materials — hexagonal boron nitride (hBN) optically-active spin defects at room temperature, and moiré physics in TMD heterostructures. He is co-founder and CSO of Nu Quantum Ltd.
Bartholomew trained with Sellars (ANU) and Faraon (Caltech) and runs the Quantum Integration Laboratory, which works on rare-earth ions (erbium, europium, ytterbium) in crystals and in nanophotonic devices. Rare-earth ions have the longest optical and spin coherence times of any solid-state emitter, which makes them simultaneously the best optical quantum memories and, less obviously, extremely good sensors: the group works on rare-earth-based microwave and RF quantum sensing, on-chip integration of ions with photonic and superconducting circuits, and telecom-band spin-photon interfaces. 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 — rare-earth ensembles are the closest solid-state analogue to NV ensembles, with narrower optical lines and longer coherence but cryogenic operation; protocols like DEER and dynamical-decoupling-enhanced sensing at pT/sqrt(Hz) map across directly. This is one of the best fits at Sydney for a solid-state spin-sensing candidate.
Barz builds integrated photonic quantum information processors - multi-photon entanglement, verified/blind quantum computing, and photonic networks - with direct relevance to photonic quantum metrology and distributed quantum sensing. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work contributes photonic-network and multiphoton-metrology tools.
Brune leads the Circular Rydberg Atom / Cavity QED group at LKB (Collège de France site), continuing the work of Serge Haroche (Nobel 2012). Note: Brune is employed by ENS, not Sorbonne Université; postdoc contracts are typically ENS/CNRS. Research directions: (1) Circular Rydberg atoms — atoms in extremely high principal quantum number states (n~50) with extremely long radiative lifetimes (~30 ms) and large dipole moments; (2) Cavity QED quantum sensing — single circular atoms probe the microwave field in a superconducting cavity photon-by-photon via quantum non-demolition measurement; (3) Quantum state engineering — generating Fock states, Schrödinger cat states, and entangled atom-field states in the cavity; (4) Tests of quantum complementarity — observing decoherence of mesoscopic superpositions in real time as a probe of quantum-to-classical transition. The 'quantum radio receiver' using single atoms to sense individual microwave photons is a landmark quantum sensing demonstration.
Michel Brune leads the Rydberg atoms / cavity QED group at LKB. Research: (1) circular Rydberg atoms trapped in high-finesse microwave cavities — quantum non-demolition measurement of photons, quantum state engineering; (2) fundamental quantum optics: decoherence, entanglement, quantum jumps, Schrödinger cat states; (3) quantum sensing of cavity fields with single atoms as probes. This group pioneered cavity QED experiments leading to the 2012 Nobel Prize (Haroche). Brune heads the laboratory.
Alex Clark's group works at the interface of quantum science and technology, focusing on: (1) quantum imaging with undetected photons (mid-IR sensing at 3.28 µm using CMOS cameras and entangled photons — QIUP technique); (2) single-molecule photon sources (molecules coupled to nanophotonic cavities); (3) quantum memory protocols (ORCA and ATS in atomic vapours for telecom-band photon storage); (4) integrated photonics for quantum sensing. Director of QET Labs; Work Package Leader in three UK Quantum Technology Hubs.
Specializes in quantum information and hybrid quantum systems. Directions: (1) superconducting qubit quantum computing and error correction; (2) hybrid quantum systems coupling superconducting qubits to mechanical resonators, spin systems, and optical photons; (3) quantum-limited microwave amplification; (4) co-PI DARPA QuSeN — quantum sensing of neutrinos via phonon-coupled SC qubit sensors (2025). Director Pritzker Nanofabrication Facility (PNF). AAAS and APS Fellow.
Deleglise works on cavity optomechanics and microwave-to-optical photon transduction, aiming to coherently interconnect superconducting-circuit and optical-photon quantum-network nodes; he is also affiliated with LPENS' Quantic team on circuit-QED and bosonic-code quantum error correction.
Dotsenko is a permanent member of LKB's Rydberg-atom cavity-QED team (successor to Haroche/Brune's circular-Rydberg-atom programme), using long-lived circular Rydberg states strongly coupled to microwave photons in high-Q cavities for quantum non-demolition measurement, entanglement generation, and microwave-photon-number quantum sensing.
Eggleton directs the Institute of Photonics and Optical Science and runs one of the world's leading groups on stimulated Brillouin scattering in integrated photonic circuits — the coherent interaction of light with GHz acoustic phonons in a chalcogenide or silicon waveguide. The consequences are a chip-scale microwave photonic toolbox (ultra-narrowband filters, true time delay, RF spectral analysis), photon-phonon memory, and, through the Jericho Smart Sensing Laboratory, translation into deployed sensing platforms. 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 — Brillouin optomechanics is a distinct route to the same goal — reading a weak signal out of a high-Q, low-loss resonator at the quantum noise floor — and the group's phonon-photon coupling is strong enough that quantum optomechanical operation is now within reach. Very large, very well-resourced group with extensive industry and defence funding; a candidate would be one of many.
