Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

Add Yahoo as a preferred source to see more of our stories on Google. This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum ...

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...

Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly ...

Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

A Vermont research team has cracked a 90-year-old puzzle, creating a quantum version of the damped harmonic oscillator. By reformulating Lamb’s classical model, they showed how atomic vibrations can ...

A quantum computer has reached new heights. The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in ...
