An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists ...

For nearly a century, some of the simplest questions in quantum theory have stubbornly resisted clean answers, turning basic ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

Does quantum physics place limits on the extent to which we have free will? This long-debated question stems from the way different physicists interpret the mathematics of quantum theory, but now ...

Two African science journalists – Paul Adepoju and Mkhululi Chimoio – have won the “ Quantum Pitch Competition ”, organized by Physics World and Physics Magazine to mark the International Year of ...
