Optimal quantum superresolution for full distance between incoherent optical sources in two dimensions

2025 · arXiv (Cornell University)

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 superresolution that can break this limit and achieve nonvanishing …
