Works on quantum optics and precision atomic physics, including superradiant lasing for next-generation atomic clocks and fundamental studies of light-atom interaction.

Ye's group operates the world's most precise strontium optical lattice clocks (now entanglement-enhanced), pioneered optical frequency combs and cavity-enhanced comb spectroscopy, demonstrated the thorium-229 nuclear clock transition, and studies ultracold polar molecules for precision measurement and quantum science. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.

Tarik Yefsah's group at LKB studies strongly interacting ultracold Fermi gases. Research: (1) Fermi gas mixtures — quantum simulation of condensed matter phenomena (BCS-BEC crossover, Fermi polaron); (2) quantum gas microscope experiments imaging individual atoms in optical lattices; (3) novel quantum phases in Fermi-Hubbard systems ('fermionic waltz' publication 2026). Relevant to quantum simulation and quantum gas-based sensing.

Yelin is a theorist in quantum optics and quantum information whose work includes coherent line-narrowing theory for diamond NV centers, superradiant/cooperative effects in Rydberg systems and molecular ensembles, and quantum control of ultracold polar molecules. Included as theoretical support underpinning several quantum-sensing platforms (NV coherence, superradiant clocks) rather than as an experimentalist herself; she holds a joint appointment at the University of Connecticut.

Develops nanophotonic optical biosensors and spectral bioimaging techniques (metasurface/photonic-crystal based) for label-free, high-sensitivity molecular detection.

Yildiz uses nanometer-precision single-molecule fluorescence and optical/magnetic tweezers (FIONA-type localization) to resolve the stepping mechanisms of cytoskeletal motor proteins such as myosin, kinesin, and dynein in living cells.

Andrew Young's group develops solid-state quantum photonic systems, focusing on deterministic single photon emitters and spin-photon interfaces. Research: (1) quantum dot and colour-centre emitters coupled to cavities and waveguides for near-unity efficiency; (2) spin-photon interfaces for quantum repeaters; (3) cavity quantum electrodynamics for quantum networking. Part of Quantum Communications Hub.

Studies computational classical and quantum electrodynamics, quantum optics, topological photonics, and integrated photonics, including radiative cooling and visual perception applications.

Yzombard works on laser-cooling techniques for exotic ions and antimatter precursors as part of the GBAR (Gravitational Behaviour of Antihydrogen at Rest) collaboration, aiming to measure the free-fall acceleration of antihydrogen as a fundamental test of the equivalence principle.

Iman Esmaeil Zadeh develops superconducting nanowire single-photon detectors (SNSPDs) and reconfigurable nano-photonic circuits. Research: (1) integrated SNSPDs with on-chip photonic waveguides and circuits for quantum optics experiments; (2) high-efficiency, low-timing-jitter SNSPDs for quantum communication and quantum sensing; (3) reconfigurable nano-photonic quantum circuits. Key enabler for quantum photonic sensing and quantum network experiments.
