Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, ...

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 ...

Those of us who grew up watching Luke and Leia on screen have probably wondered at one point or another why we don’t have lightsabers. The basic reason why is because the photons that make up light do ...

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 ...

Scientists have used an eye implant to improve the vision of dozens of people left functionally blind by age-related macular ...

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, ...
