In 2022, the Physics Nobel prize was awarded for experimental work showing that the quantum world must break some of our fundamental intuitions about how the universe works. Many look at those ...

Quantum coherence underpins the ability of light to exhibit wave-like interference effects and to maintain fixed phase relationships across spatial and temporal degrees of freedom. In quantum optics, ...

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 ...

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 ...

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 ...

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 ...
