Physicists at the Max Planck Institute of Quantum Optics have managed to entangle more than a dozen photons efficiently and in a defined way. They are thus creating a basis for a new type of quantum computer.

Following a novel technique, the researchers generated up to 14 entangled photons in an optical resonator, which can be…

At TU Wien (Vienna) and The Hebrew University of Jerusalem, a "light trap" was developed in which a beam of light prevents itself from escaping. This allows light to be absorbed perfectly.
