Alessandro Fedrizzi is in the School of Engineering & Physical Sciences, Heriot-Watt University, Edinburgh EH14 AS, UK. Read the paper: Energy–speed relationship of quantum particles challenges ...

An international team has confirmed that large quantum systems really do obey quantum mechanics. Using Bell’s test across 73 qubits, they proved the presence of genuine quantum correlations that can’t ...

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...

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 ...

Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger's cat analogy, ...

John Clarke, Michel H. Devoret and John M. Martinis were recognized for work that made behaviors of the subatomic realm observable at a larger scale. By Katrina Miller and Ali Watkins John Clarke, ...

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 ...

The 2025 Nobel Prize in physics has been awarded to a trio of scientists – a Briton, a Frenchman and an American – for their ground-breaking discoveries in the field of quantum mechanics. John Clarke, ...
