A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

This is the International Year of the Quantum, celebrating quantum science and its many applications. It also marks the centenary of Werner Heisenberg’s seminal work in modern physics. In recent years ...

Scientists have long known that light can sometimes appear to exit a material before entering it—an effect dismissed as an illusion caused by how waves are distorted by matter. Now, researchers at the ...

Quantum computers are supposed to revolutionize scientific computing, but researchers have recently shown that a classical computer can sometimes outperform them. Using advanced mathematical models, a ...

A hidden world of quantum metrologists ensure that everyday devices perform safely and correctly, but their work is never ...

Scientists have demonstrated after decades of theorising how light interacts with vacuum, recreating a bizarre phenomenon predicted by quantum physics. Classical physics predicts that light beams pass ...

The concept of quantum computing refers to the use of quantum mechanical phenomena in a way that deals with both entangled ...

The US Defense Advanced Research Projects Agency (DARPA) has assembled a team of researchers to make communication networks more secure by injecting them with quantumness ...
