Quantum computers get a lot of attention, even though they are not ready for prime time, but quantum sensors are already ...

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

Dark matter is an elusive form of matter that almost never emits, absorbs or reflects light, while only weakly interacting with regular matter. These properties make it very difficult to detect using ...

Researchers have developed a technique that makes high-dimensional quantum information encoded in light more practical and reliable. The advancement could pave the way for more secure data ...

Quantum mechanics would allow the Universe to eventually tunnel to the lowest energy state, or the ‘true’ vacuum, and that process would result in a cataclysmic global event. (CREDIT: Professor Zlatko ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

What if wormholes were never cosmic tunnels at all? New research suggests Einstein and Rosen’s famous “bridge” may actually reveal something even stranger: time itself could flow in two directions at ...

To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.
