The SpooQy Lab

The team has two full-time research positions available:

  1. A postdoctoral position in experimental quantum optics to lead development of our next generation of entangled photon sources and applications. The job application is available at

  2. A research position in developing free-space optical communication terminals with self-aligning capability. PhD qualification is not required for this position. The job application is available at

We are looking forward to hearing from you!

PhD studentships are available - please contact us. More information is available at ,

  • Subash Sachidananda will be speaking at Photonics West 2022 on re-configurable active quench circuits for single photon detectors.

  • SpooQy-1 re-entered Earth's atmosphere in late 2021. Thanks for all the data, SpooQy-1!

  • A study on the realistic rates of QKD from a nanosatellite has been Photonics West 2021.

  • In 2021, a possible design for the optical front end of a QKD nanosatellite has been presented with our colleagues from MIT, U. Arizona and SpeQtral. See the publication.

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.
