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 ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

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

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

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

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...
