Quantum-Limited Distance Estimation in Three-Dimensional Optical Superresolution
Junyan Li, Shengshi Pang
Quantum superresolution reveals that the vanishing of separation sensitivity in conventional imaging below the Rayleigh limit does not necessarily indicate a fundamental loss of in…

Optimal quantum superresolution for full distance between incoherent optical sources in two dimensions
Junyan Li, Shengshi Pang
The Rayleigh criterion has long served as a fundamental limit for the resolution of optical imaging. Recent advances in multiparameter quantum metrology have led to quantum superre…
