Light behaves as both a wave and a particle, a paradox that has resisted complete explanation for over a century despite ...

Researchers have used a 350-year-old theorem to better understand the strange nature of light. The team took a theorem used for describing pendulums and substituted the brightness of light in for what ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

In 1964, physicist John Bell formulated what became known as Bell's Theorem, showing that if quantum mechanics is correct, ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local ...

Irish physicist William Rowan Hamilton’s pioneering work contained hints of the enigmatic wave–particle duality that governs ...

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

In a first-of-its-kind experiment, researchers have captured quantum uncertainty in real time using ultrafast pulses of light ...

In a striking display of quantum physics, a team of researchers has recreated one of science’s most legendary experiments—with unprecedented precision. At MIT, scientists cooled thousands of atoms to ...
