You can’t divide the indivisible, unless you use quantum mechanics. Physicists have now turned to quantum effects to split phonons, the smallest bits of sound, researchers report in the June 9 Science ...

One of the most perplexing aspects of quantum mechanics is that tiny subatomic particles don't seem to "choose" a state until an outside observer measures it. The act of measurement converts all the ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the ...

For many of us, advanced physics can be tough to understand to begin with, which makes it all the more impressive whenever someone earns a Nobel Prize for advancing the field even further. The latest ...

On the centennial of modern quantum mechanics, the Nobel Committee awarded the year’s most prestigious physics prize to an experiment that demonstrated how quantum effects play out on large ...

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 ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...
