Quantum telescopes: Planet-sized telescopes could be possible using quantum technique

Date:


Huge networks of interconnected telescopes may run into image-sharpening problems that classical physics can’t handle. Accounting for the quantum properties of starlight could allow astronomers to get past these constraints

Quantum computers that can catch their own mistakes could make it possible to build huge telescopes the size of a planet. The approach would allow astronomers to get past constraints with current telescopes to clearly view distant objects in space.

Astronomers trying to take images of faraway stars and planets are at the mercy of whatever faint light reaches their telescopes. They can increase the resolution by using arrays of interconnected telescopes called astronomical interferometers. However, to obtain sharp …
