John Clarke, Michel Devoret, and John Martinis awarded Nobel Prize 2025 for discoveries driving quantum computing.

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

In the world of quantum physics, the rules that govern reality behave in ways that challenge what we think we know. Particles can be in two places at once. Actions on one particle can instantly affect ...

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 ...

One of the quietest places in the universe is an unremarkable room on the southern coast of the UK. Here, in one of the University of Southampton’s physics labs, overseen by Hendrik Ulbricht, a ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Quantum computing may sound like something out of a science fiction movie. However, large companies such as Google, IBM, and Microsoft are investing heavily in quantum computing research and ...
