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.

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 rare-earth-ion-doped crystal platforms for quantum internet hardware. Directions: (1) Er3+-doped crystal quantum memories with >1 ms coherence time in nanophotonic waveguides; (2) microwave-to-optical quantum transduction using Er spins coupled to superconducting resonators; (3) photon-number-resolving detectors for quantum communication; (4) integrated rare-earth nanophotonic circuits on thin-film LiNbO3. Key goal: scalable room-temperature-compatible quantum repeater nodes.

Zubairy is a quantum-optics theorist working on quantum imaging beyond the diffraction limit, quantum-coherence-based sensing, entanglement distribution and quantum information protocols. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work frames the theoretical limits that spin-ensemble sensors approach.
