Researchers set 'ultrabroadband' record with entangled photons

Quantum entanglement—or what Albert Einstein once referred to as "spooky action at a distance"— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one ...

Light to break bandwidth ceiling

The rise of big data and advances in information technology has serious implications for our ability to deliver sufficient bandwidth to meet the growing demand.

A 100-year-old physics problem has been solved

At EPFL, researchers challenge a fundamental law and discover that more electromagnetic energy can be stored in wave-guiding systems than previously thought. The discovery has implications in telecommunications. Working around ...
