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 ...

The first direct visualization of the shape of a photon has been created. These particles of light are impossible to photograph, but physicists at the University of Birmingham have now calculated ...

Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through the air instead of relying on radio waves or copper traces. The result is a ...
