A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold object to a hot one, provided the right quantum conditions are in place. This ...

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 key distribution promises ultra-secure communication by using the strange rules of quantum physics to detect eavesdroppers instantly. But even the most secure quantum link can falter if the ...

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

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow ...

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

Physicists have watched a quantum fluid do something once thought almost impossible: stop moving. In experiments with ultra-thin graphene, researchers observed a superfluid—normally defined by its ...

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 ...

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 ...
