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 ...

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be ...

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

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

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors.

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 ...

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

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, ...

Quantum technology holds great promise: Quantum computers are expected to revolutionize database searches, AI systems, and computational simulations. Today already, quantum cryptography can guarantee ...
