At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.

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 ...

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

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

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

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 ...

A team of physicists has reimagined one of science’s most iconic experiments—but in the dimension of time. Researchers at Imperial College London have taken the classic double-slit test and turned it ...

Quantum materials can behave in surprising ways when many tiny spins act together, producing effects that don’t exist in single particles.

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

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Let me tell you about my book "Fields and Their Quanta: Making Sense of Quantum Foundations," published last year by Springer. It's technical, but I'll describe it in English. Scientists agree the ...
