A ‘quantum processor’ has solved a physics problem on the behaviour of magnetism in certain solids that would take the largest conventional supercomputers hundreds of thousands of years to calculate.

Quantum entanglement, a bewildering phenomenon where particles become interconnected regardless of the distance separating them, challenges our fundamental understanding of reality. It has puzzled ...

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 ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

In commemoration of the 100th anniversary of modern quantum mechanics, a survey asked physicists for their takes on some hot questions in quantum theory. Reading time 4 minutes In July 1925—exactly a ...

John Clarke, Michel H Devoret and John M. Martinis are announced this year's Nobel Prize winners in Physics, by the Royal Swedish Academy of Sciences at a press conference in Stockhom, Sweden October ...

Here’s what you’ll learn in this story: The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it. While most physicists agree that human ...

With global initiatives, new funding rounds, the achievement of key technical milestones and the portent of scientific breakthroughs, the International Year of Quantum is off to an auspicious start.

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...
