Optical measurements that can achieve the fundamental quantum limits have the potential to
improve the imaging of subdiffraction objects in important applications, including optical …

We establish fundamental bounds on subwavelength resolution for the radar ranging
problem,“superradar.” Information-theoretical metrics are applied to probe the resolution …

Quantum super-resolution involves resolving two sources below the Rayleigh limit using
quantum optics. Such a technique would allow high-precision inter-satellite positioning and …
