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 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 ...

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

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

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

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...
