What if a quantum device could make time flow in two opposite directions at once? Physicists are exploring this mind-bending ...

Electrons inside a diamond have given a floating, centimeter-sized device a quantum nudge, opening a new path toward testing ...

(da-kuk/E+/Getty Images) Quantum computers promise an incredible leap forward in terms of performance, but a lot of that ...

For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser ...

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 ...

The ATLAS collaboration found strong evidence that Z bosons produced in Higgs boson decays are quantum-entangled, extending ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

Measuring gravitational analogues of quantum phenomena could lead to high-precision measurement of gravitational forces, according to a theoretical proposal. Micromuffins. The 1-µm-wide ...

Modern physics is weird. Quantum mechanics gives us Schrödinger's cat, simultaneously alive and dead. Relativity gives us the twin paradox, where a spacefaring twin ages more slowly. But what if we ...
