As far as particles of light are concerned, the collective is more important than the individual. When they get to decide ...

A stable ‘frequency comb’ of photons with discrete colours has been generated on a microscale chip by removing copper contaminants from the circuit. The development of PICs was enabled by advances in ...

What is the purpose of light? How does light work? Why does light exist? This video explores the longstanding debate over ...

New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication ...

A consortium of German researchers has successfully transmitted individual photons from a moving aircraft, captured them in a ...

Quantum radar is an emerging technology that exploits the strange phenomenon of quantum entanglement to detect objects that ...

Ars Technica's Chris Lee has spent a good portion of his adult life playing with lasers, so he's a big fan of photon-based quantum computing. Even as various forms of physical hardware like ...

Photons, the elementary particles that make up light, are known to be fast, weightless and to not interact with each other. But in new experiments, physicists at MIT and Harvard have now created a new ...

Up until the mid-20 th century, light was pretty ordinary. Yes, it was both a particle and a wave, but it didn’t do anything very weird. Then scientists, under-employed after the end of World War II, ...
