Department(s)/lab(s): Physics โ€“ QOLS / Centre for Cold Matter | Centre for Cold Matter โ€“ Quantum Navigation @ Imperial
Summary:

Cotter leads the Quantum Navigation research stream at Imperial's Centre for Cold Matter. He develops compact, fieldable cold-atom inertial sensors for GPS-denied navigation.

Department(s)/lab(s): School of Physics | Superconducting Quantum Circuits Laboratory @ USyd
Summary:

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 โ€” DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity โ€” 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 โ€” and beat โ€” the pT/sqrt(Hz) regime. Newly established, well-equipped lab; high autonomy for a postdoc and active recruitment as the lab builds out.

Department(s)/lab(s): School of Physics (joint with Electrical and Electronic Engineering) | Crozier Nanophotonics Laboratory @ UMelb
Summary:

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 โ€” DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity โ€” 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.

Department(s)/lab(s): Electrical and Computer Engineering | de Leon Lab @ Princeton
Summary:

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.

Department(s)/lab(s): Physics โ€“ QOLS / Centre for Cold Matter | Centre for Cold Matter โ€“ Quantum Technology & Dark Matter (Devlin) @ Imperial
Summary:

Devlin is a Royal Society URF at the Centre for Cold Matter building a new experiment to detect axion and dark matter particles. His prior work at CERN's BASE collaboration (Penning trap antiproton experiment) used the ultra-sensitive superconducting detection circuit of a cryogenic Penning trap to set new constraints on axion-like particle couplings to photons (~2.79 neV/cยฒ range; PRL 2021). At Imperial he is developing a Penning trap single-photon counter concept using a single trapped electron to detect 30โ€“60 GHz photons from axion-photon conversion in a strong magnetic field (arXiv 2601.05472, March 2026), targeting axion masses of 124โ€“248 ฮผeV. This approach could overcome the standard quantum noise limit that hampers conventional haloscope searches at high mass. Active PDRA posting open May 2025.
