FAQ on "Quantum theory of superresolution for two incoherent optical point sources"

We study the probabilistic nature of quantum mechanics and its implications for sensing applications, such as optical imaging, interferometry, spectroscopy, optomechanical sensing, gravitational-wave detection, and magnetometry.

Our group is housed in the Department of Electrical and Computer Engineering at the National University of Singapore. We are also affiliated with the Computational Nanoelectronics and Nanodevices Laboratory (CNNL) and the Department of Physics.

Before you ask, we are NOT affiliated with the Centre for Quantum Technologies.
