Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out. But new in the way they share ...

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...
