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.
Crozier holds a joint Physics/Electrical Engineering chair and runs a nanophotonics laboratory spanning plasmonic and dielectric metasurfaces, on-chip optical trapping and manipulation of nanoparticles and cells, mid-infrared spectroscopy and detection with metasurface-enhanced and colloidal-nanocrystal devices, and light emission from 2D semiconductors. The unifying theme is engineering the local optical density of states to increase the signal available from a very small number of emitters or molecules. 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 plasmonic and dielectric antenna work is the same physics used to raise photon collection efficiency and hence the shot-noise floor of NV-ensemble magnetometers operating at pT/sqrt(Hz). Note: a substantial fraction of the group's output is device fabrication rather than sensitivity-limited measurement, which is a caveat against the stated preference.
Curry's group works on advanced electronic materials with emphasis on quantum technology applications. Research directions: (1) Single-ion implantation and detection — using P-NAME (Manchester's unique instrument for ion implantation at 20 nm accuracy) to deterministically place single rare-earth ions (Er3+, Pr3+) in photonic substrates for quantum memory and sensing; (2) Er:Si and Er:SiO2 photonics — developing silicon-compatible Er-doped waveguides and cavities emitting at 1.5 µm for quantum network interfaces; (3) Colloidal quantum dots for sensing — photon-number-resolved detection using InAs QDs; (4) Ion beam technologies — SIMS and focused ion beam for quantum material characterization and fabrication. Access to P-NAME facility is unique in UK.
Cushing's group develops quantum-light (entangled-photon) spectroscopies and tabletop attosecond/X-ray methods to probe electron and energy dynamics with quantum-enhanced sensitivity and resolution, including entangled-photon spectroscopy and imaging beyond classical shot-noise limits. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.
Jean Dalibard's BEC group at LKB studies quantum gases, BEC, and strongly correlated quantum systems. Research: (1) 2D Bose gases and Berezinskii-Kosterlitz-Thouless transition; (2) gauge fields for neutral atoms — synthetic magnetism; (3) quantum simulation with ultracold atoms. Dalibard is a foundational figure in cold-atom physics; his group at LKB/Collège de France is relevant through quantum gas experiments tied to quantum simulation and precision measurement. Borderline case included given BEC foundations for sensing.
A new experimental group using alkaline-earth-like atoms in programmable optical tweezer arrays to improve optical-qubit atomic clocks and develop quantum-enhanced metrology and many-body control; actively building the lab and recruiting students and postdocs. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.
The de Leon lab engineers nitrogen-vacancy and other color centers in diamond and wide-bandgap materials as solid-state quantum sensors and qubits, spanning materials growth and surface chemistry, nanophotonic integration, and magnetic-field/thermal sensing of quantum materials, alongside a parallel effort on superconducting qubit noise and loss. This builds on the broader tradition of ensemble NV magnetometry (DEER, NMR, T1 relaxometry) that has reached pT/sqrt(Hz)-class sensitivities, which de Leon's group extends toward single- and few-spin scanning-probe magnetometry of correlated electron materials.
de Lera Acedo heads the Cavendish Radio Astronomy and Cosmology group and is PI of the REACH experiment, a global 21-cm signal radiometer deployed in the Karoo desert, South Africa, targeting detection of the redshifted hydrogen signal from the Cosmic Dawn (z≈7.5–28). He has a PDRA opening for 21-cm cosmology data analysis. Research spans novel antenna design, ultra-low-noise receiver calibration (achieving ~80 mK RMSE), Bayesian foreground modelling, and RFI mitigation. He also leads the CosmoCube space mission concept for lunar-orbit 21-cm observations and is active in SKA development and HERA. He is actively hiring postdocs (PDRA posting live in 2025).
Simone De Liberato's Quantum Theory and Technology group explores quantum electrodynamics in semiconductor systems. Research: (1) ultrastrong and deep-strong light-matter coupling in polariton and circuit QED systems; (2) mid-infrared polariton physics with potential sensing applications; (3) virtual photon condensation and vacuum fluctuations in quantum materials; (4) positronium density measurements using polaritonic effects. Relevant to quantum sensing via strong coupling platforms.
Defienne leads the Quantum Imaging Paris group at INSP, using spatial correlations and Hong-Ou-Mandel-type interference between entangled photon pairs to build microscopes that see through scattering media and correct optical aberrations without a spatial light modulator. His ERC-funded CORAMI project develops correlation-based adaptive optics as a universal add-on module for existing microscopes, targeting deeper (>1 mm), higher-contrast in-vivo imaging for neuroscientists, dermatologists, and ophthalmologists.
