The SpooQy Lab

Congratulations to Zhang Xingjian Spook#7 on a successful defense of the PhD thesis!

SpeQtre has launched! Plans started in 2018 in SpooQyLab. Glad to see it in space.
Entanglement distribution over 155 km of metropolitan fiber using a nanophotonic Si chip is now published in Newton! https://doi.org/10.1016/j.newton.2025.100303
Boosting classical and quantum nonlinear processes in ultrathin van der Waals materials. How thin can we make nonlinear materials for quantum light emission? In collaboration with Gao Weibo, and published in Nature Communications.
SpooQy-1 continues to contribute to science. In this paper with UK-based collaborators we report on the observation of radiation damage for the single photon detectors on the satellite, and developed a model that predicted the radiation damage observed. This can be very useful for future space missions. See the results in Nature Communication Physics 8, 118 (2025).

We are a multi-disciplinary group at the Centre for Quantum Technologies in Singapore. We are located on the National University of Singapore campus. Our work leverages optical technology for building compact, rugged & effective optical entanglement systems used for testing fundamental physics and demonstrating quantum-assisted applications. We work with a wide range of optical tools, and have an active interest in nonlinear optics including bulk and waveguide materials. Systems integration (optics, electronics & mechanical design) is a key theme of our work and undergraduate students are encouraged to take part in our projects.
