Interaction-free, single-pixel quantum imaging with undetected photons
To capture an image of an object, a photographer typically requires a source of light interacting and scattering away from that object of interest, and a method to detect the light being scattered away from that object, as ...
The first lab-created 'quantum abacus'
Do you want to know whether a very large integer is a prime number or not? Or if it is a "lucky number"? A new study by SISSA, carried out in collaboration with the University of Trieste and the University of Saint Andrews, ...
