Quantum-optimal detection of one-versus-two incoherent sources with arbitrary separation
Xiao-Ming Lu, Ranjith Nair, Mankei Tsang
We analyze the fundamental resolution of incoherent optical point sources from the perspective of a quantum detection problem: deciding whether the optical field on the image plane…
Quantum limit for two-dimensional resolution of two incoherent optical point sources
Shan Zheng Ang, Ranjith Nair, Mankei Tsang
We obtain the multiple-parameter quantum Cramér-Rao bound for estimating the transverse Cartesian components of the centroid and separation of two incoherent optical point sources…
Far-field Superresolution of Thermal Electromagnetic Sources at the Quantum Limit
Ranjith Nair, Mankei Tsang
We obtain the ultimate quantum limit for estimating the transverse separation of two thermal point sources using a given imaging system with limited spatial bandwidth. We show via…
Semiclassical Theory of Superresolution for Two Incoherent Optical Point Sources
Mankei Tsang, Ranjith Nair, Xiao-Ming Lu
Using a semiclassical model of photodetection with Poissonian noise and insights from quantum metrology, we prove that linear optics and photon counting can optimally estimate the…
