Chen (PhD, Max Planck Institute of Quantum Optics) develops chip-scale frequency-comb sources for precision metrology and dual-comb spectroscopic sensing, and is now extending integrated thin-film lithium-niobate photonics toward on-chip squeezed-light generation for quantum-enhanced sensing alongside photonic AI accelerators. The lab is actively recruiting postdocs.
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.

This group is directly relevant to quantum-enhanced sensing with squeezed light.
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.

Malaney works on quantum communications with an emphasis on the satellite channel: continuous- and discrete-variable QKD through atmospheric turbulence, entanglement distribution from space, and the use of Gaussian and squeezed states as the carriers. A distinct thread is quantum-enhanced sensing and localisation — quantum illumination and quantum radar — where entangled probe states are used to detect weakly-reflecting targets in noisy backgrounds. 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 work belongs to the nonclassical-light arm of the search: it addresses whether squeezing and entanglement can be preserved through a lossy channel well enough to deliver a real metrological advantage, which is the practical question that determines whether quantum-enhanced sensing can ever beat a well-engineered shot-noise-limited pT/sqrt(Hz) device. Largely theory/simulation with some experimental collaboration.
