Mysteries And Surprises In Quantum Physics:

Scientists report manipulating and controlling single atoms and single photons interacting in a cavity, which is a box made of highly reflecting walls. The result means that it is now possible repeatedly to extract information from the same photon. This is important because the major part of all information we get from the universe come from light. "Developing a new way of 'seeing' could have applications in quantum science," said researcher, Prof. Haroche. "A photon could share its information with an ensemble of atoms to build up an 'entangled state' of light or matter".
