De Sterke is a theorist-experimentalist of nonlinear and structured photonics. The group's signature recent contribution is the pure-quartic soliton: by engineering the dispersion of a waveguide so that the group velocity depends on the third power of frequency, they produce solitons with a different energy-width scaling from conventional ones, with direct consequences for mode-locked laser and frequency-comb design. The group also works on topological and non-Hermitian photonics and on THz metamaterials. 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 relevance is to the light side of the search rather than the spin side: dispersion-engineered comb and soliton sources are the local oscillators and reference clocks that any optical readout of a pT/sqrt(Hz) sensor ultimately depends on. Borderline inclusion; kept for the fundamental-light-physics criterion.

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.

PREFERRED. Evans leads work on frequency-dependent squeezed-light injection and low-thermal-noise optics that has pushed Advanced LIGO below the standard quantum limit across its full detection band, and he leads the US design effort for the next-generation Cosmic Explorer gravitational-wave observatory. This is squarely quantum-enhanced sensing at a fundamental-physics facility scale rather than a device-fabrication program.

Fejer develops engineered nonlinear-optical materials (periodically poled crystals, low-mechanical-loss optical coatings) used to generate squeezed light and to reduce thermal noise in precision interferometers, contributing core technology to the squeezed-light upgrades deployed in Advanced LIGO.

The Hosseini Lab (Quantum Atom Optics) investigates light–atom interactions in rare-earth crystals, room-temperature gases, and nanophotonic structures. Directions: (1) Quantum optical memories in Tm³⁺:YAG and Er³⁺-doped solids using atomic frequency comb (AFC) and gradient echo memory (GEM) protocols for telecom-wavelength quantum networking; demonstrated efficient storage of multi-dimensional telecom photons (Optica Quantum 2025, Phys. Rev. Appl. 2025); (2) Cooperative/collective light–matter interactions in periodic rare-earth ion arrays in nano/micro-photonic structures (collaboration with Oak Ridge NL, Aydin group) for enhanced quantum memory coherence; (3) Quantum squeezed light — applied to enhanced thermoreflectance sensing of electronic hotspots (Appl. Phys. Lett. 2024); (4) Coherent levitation of macroscopic sensors (DARPA YFA 2024, $500k): magnetic and optical trapping of mm-scale objects as high-Q oscillators for magnetometry, vibrational sensing, accelerometry, inertial, and force sensing. Lab actively seeking postdocs in integrated photonics, quantum memory, and levitation sensing (2024–2025). ASEE Curtis W. McGraw Research Award 2026.

Prof. Kumar's group spans classical and quantum optics across three inter-related areas: (1) Quantum Fiber Optics — generation and distribution of entanglement (photon-pair, multi-photon) over fiber networks, quantum key distribution, and first-ever quantum teleportation over active internet-carrying fiber; (2) Nonlinear Quantum Optics — squeezed light and twin-beam (two-mode squeezed) state generation via fiber-based four-wave mixing and χ⁽²⁾ processes, with applications to sub-shot-noise interferometry, quantum-enhanced imaging, and quantum communication; (3) Photon-entanglement-enhanced precision measurement and optical communications. AT&T Professor of Information Technology; INQUIRE Executive Committee member.

Lvovsky works broadly across quantum and optical technology, from foundational quantum optics (non-classical light states) to quantum-enhanced imaging; recent work combines spatial-mode demultiplexing with image scanning microscopy to push lateral resolution beyond the classical diffraction limit.

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.

PREFERRED. Mavalvala's research (now balanced against her role as Dean of the School of Science) centers on gravitational-wave detection and quantum measurement science, including the original squeezed-light and quantum-noise work at LIGO that she led together with Matthew Evans. Given her administrative role, active new postdoc hiring in her own group is uncertain and should be confirmed directly.

Palomba works on nonlinear nanophotonics and plasmonics: exploiting the extreme field confinement of metallic and hybrid nanostructures to obtain efficient frequency conversion, second- and third-harmonic generation and four-wave mixing in device footprints far smaller than conventional nonlinear optics allows, and integrating these with silicon photonics. The applications the group targets include on-chip nonclassical light generation and nanoscale sensing. 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 field-enhancement physics is the same toolkit used to build the nanoantennas that raise photon collection from single NV centres and thereby move single-defect sensing toward the pT/sqrt(Hz) performance of ensembles. Borderline inclusion; the group is device-centred, which cuts against the stated preference.
