Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

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 ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

This massive particle could serve as the connection between dark matter and the everyday matter that comprises stars, planets and us. When you purchase through links on our site, we may earn an ...

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, ...

For the first time, scientists have watched groups of three photons interacting and effectively producing a new form of light. In results published in Science, researchers suggest that this new light ...

Using photonic chips to control single photons in waveguides is a promising route to technologies based on the photons'quantum properties. The ability to measure entanglement on such chips is a key ...

Seven billion years ago, three cosmic travelers set out together on an epic journey to Earth. They've just arrived, and they bring news of the great beyond. Their surprising story could overturn ...

Radar, at its simplest, involves sending out pulses of radiation that reflect off an object. The reflected signal is detected, and the time of flight is measured. The time of flight is then translated ...
