Theory Postdoc Position Available

[update on 29 March 2021: The position is now closed.]

[update on 28 March 2020: We can now hire only Singapore citizens and long-term pass holders. If you need a new work pass, you need to stay in Singapore while it is being processed. The position will remain open until filled.]

My group has a theory postdoc position that needs to be filled as soon as possible. It is not attached to any project so the postdoc will be free to work on any topic as long as it is of mutual interest. My current interest is in quantum estimation theory, quantum measurement theory, and quantum optics, but I am open-minded. For more information about our research activities, please see

The base salary will be SGD5,000 per month. There will be standard medical benefits and some conference travel support. For Singapore citizens or permanent residents we also provide CPF contributions on top of the salary. The funding ends on 31 March 2023.

Unfortunately we are only able to hire Singaporean citizens and long-term pass holders in the near future because of government restrictions. If you need a new work pass, you need to stay in Singapore while the application is being processed.

If you are interested, please email your CV and a one-page research statement to The position will remain available until filled or before 31 March 2021. I will contact you for further information and references if there is a need.

Please feel free to share this news with any potential candidate, and email me at if you have any question.

Quantum Theory of Superresolution for Two Incoherent Optical Point Sources

Mankei Tsang, Ranjith Nair, and Xiao-Ming Lu, Physical Review X 6, 031033 (2016) [Open Access]

“Tsang and his colleagues have provided a new perspective on the utility of quantum metrology, and they have reminded us that even in observational astronomy—one of the oldest branches of science—there are (sometimes) still new things to be learned, at the most basic level.”

—Gabriel Durkin, Viewpoint in APS Physics

“Seth Lloyd of the Massachusetts Institute of Technology in the US is impressed. ‘This is awesome work and I am amazed that it hasn’t been done before,’ he says. ‘Perhaps everyone thought it was too good to be true.’”

—quoted by Edwin Cartlidge, IoP Physics World

“Through this work we can learn more about our surroundings, both by looking outward and by looking inward. The technique Tsang’s team developed could also be applied to improving how well a microscope resolves fluorescent samples like biological molecules, drugs, or toxins. As both scales of this work moves forward, it reminds us that light is not only a tool for exploration, but also a rich source of information to explore.”

—Kendra Redmond, APS Physics Buzz
