Quantum Light Manipulation Now Possible, Say Scientists.

Scientists at the University of Sydney and the University of Basel have demonstrated the ability to manipulate and identify small numbers of interacting photons, representing an important landmark in the development of quantum technologies. The scientists could measure the direct time delay between one photon and a pair of bound photons scattering off a single quantum dot, a type of artificially created atom. This opens the door to the manipulation of what we can call 'quantum light', which can be important for applications in biological microscopy and quantum computing.
