PREFERRED. Wong's research centers on quantum and nonlinear optics, particularly high-flux, high-purity polarization-entangled and pure-state single-photon sources (including the Sagnac-interferometer entanglement source later flown on a Chinese quantum-communication satellite) for quantum key distribution and quantum information processing. By his own account he is approaching retirement in the near future, so his continued availability for a postdoc search should be confirmed directly.
Xu works on frequency-dependent squeezed-light injection for quantum-enhanced gravitational-wave detection at LIGO and on trapped-cavity atom interferometry for precision tests of fundamental physics, bridging quantum optics and atom-based inertial sensing.
Xu leads the Experimental Quantum Engineering group with a joint ETH–PSI appointment. Research directions: (1) Superconducting circuit quantum sensing — using qubits-as-sensors for detecting weak microwave signals beyond standard quantum limits, quantum non-demolition readout of photon fields; (2) Quantum error correction enabled sensing — integrating bosonic codes (cat qubits, binomial codes) into sensing protocols; (3) Quantum acoustics — coupling superconducting qubits to surface acoustic wave (SAW) resonators for hybrid quantum sensing; (4) Novel quantum hardware at PSI — leveraging PSI's infrastructure for cryogenic device fabrication and testing. Connected to the ETH–PSI Quantum Computing Hub.
Yakovlev develops label-free biomedical imaging: Brillouin micro-spectroscopy of cell/tissue viscoelasticity, impulsive stimulated Brillouin scattering, SERS and coherent-Raman diagnostics, and quantum-enhanced (photon-number-resolving, sub-shot-noise) optical imaging in collaboration with Agarwal/Scully. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides the biomedical, quantum-enhanced-imaging bridge for spin-sensor bio-applications.
Works on quantum optics and precision atomic physics, including superradiant lasing for next-generation atomic clocks and fundamental studies of light-atom interaction.
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.
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.

Key enabler for quantum photonic sensing and quantum network experiments.
Emil Zeuthen works on theoretical quantum optomechanics and quantum transduction. Research focuses on (1) figures of merit and protocols for quantum transducers (mechanical interfaces between microwave and optical domains); (2) back-action-evading measurements using optomechanical systems; (3) quantum limits for gravitational wave detection with mechanical systems in a negative-mass spin reference frame. Key QUANTOP theory collaborator bridging optomechanics and quantum sensing.
