The resolution of an optical system (like a telescope or a camera) is limited by the so-called Rayleigh criterion. An international team has broken this limit, showing that it is not a fundamental ...

Astronomers, meanwhile, can sometimes use signal processing to resolve objects that are slightly closer than the Rayleigh criterion allows. Tsang and co-workers instead used a theory known as “quantum ...
