Physicists have watched a quantum fluid do something once thought almost impossible: stop moving. In experiments with ...

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

Can a single particle have a temperature? It may seem impossible with our standard understanding of temperature, but ...

If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

In a new study published in Physical Review Letters, researchers used machine learning to discover multiple new classes of ...

The properties of a quantum material are driven by links between its electrons known as quantum correlations. A RIKEN ...

A microscopic clump of sodium has become the largest object ever to be observed as a wave, improving upon previous records by ...

I trained as a physicist, and in physics we distinguish between classical and quantum systems. Classical physics describes a ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

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