Quantum Theory of Superresolution for Two Incoherent Optical Point Sources
Mankei Tsang, Ranjith Nair, Xiao-Ming Lu
Rayleigh's criterion for resolving two incoherent point sources has been the most influential measure of optical imaging resolution for over a century. In the context of statistica…

Quantum optimality of photon counting for temperature measurement of thermal astronomical sources
Ranjith Nair, Mankei Tsang
Using the quantum Cramér-Rao bound from quantum estimation theory, we derive a fundamental quantum limit on the sensitivity of a temperature measurement of a thermal astronomical s…
