2nd Workshop on Quantum-Inspired Superresolution

Mankei Tsang, “Efficient superoscillation measurement for incoherent optical imaging,” IEEE Journal of Selected Topics in Signal Processing 11, 513-524 (2023) [arXiv PDF].

This work relates our previous works on moment estimation to the estimation of generalized Fourier coefficients in the context of superoscillation. A step towards a general quantum theory of image reconstruction.

People often asked us whether we can apply our quantum-inspired superresolution ideas to gravitational-wave detection. This paper shows that the answer is yes, if the goal is to detect a stochastic gravitational-wave background. This is because the two problems have the same random displacement model under the hood: randomly displaced photons in the case of imaging, and randomly displaced fields in the case of optomechanical detector. With the correspondence direct imaging = homodyne, SPADE = photon counting in the spectral modes, photon counting turns out to be far superior to homodyne in the same way SPADE is superior.

[Update on 1 Oct 2021: the position is now closed.]

Mankei Tsang invites applications for a postdoctoral fellow position in his group at the National University of Singapore (NUS). The main job of the fellow will be to perform theoretical or experimental research on quantum-inspired microscopy, although they may also be given freedom to work on independent projects that are of mutual interest to both the fellow and the group. For more information about the interests of the group, see https://blog.nus.edu.sg/mankei/.

The annual base salary will be 60,000–72,000 Singapore dollars, depending on the candidate’s qualifications. Medical insurance will be provided. The earliest start date is 1st July 2021. The initial contract will be 12 months long and extensible by mutual consent. The position will remain available until filled.

The applicant should have a PhD degree in Physics, Electrical Engineering, or a related discipline, a strong track record in theoretical or experimental quantum optics research, and proficiency in statistical data analysis.

A foreign candidate will need to satisfy the government COVID-19 requirements before they may be hired; see https://www.mom.gov.sg/covid-19/entry-approval-requirements.

The applicant should email a curriculum vitae to mankei@nus.edu.sg. Shortlisted applicants will be informed; they should then arrange three reference letters to be emailed to the same address. Please check https://blog.nus.edu.sg/mankei/2021/05/11/job_ad/ for any latest update about the position and email mankei@nus.edu.sg if you have any question.
