That low-frequency fuzz that can bedevil cellphone calls has to do with how electrons move through and interact in materials ...

Spin correlations in the heart of a particle collider may help crack one of the biggest mysteries known, said physicist Zhoudunming Tu.

Physicists have coaxed clusters of thousands of atoms into a delicate quantum limbo, creating a record breaking version of ...

Most physicists doubt that time exists. On this page 40 years ago, we published scientific ‘proof’ of time being illusory. We pointed out that none of the equations of physics, from Newton’s laws to ...

John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the ...

Using a 78-qubit superconducting quantum processor known as "Chuang-tzu 2.0", researchers from the Chinese Academy of ...

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 ...

The original paper by Kim et al. on the Delayed Choice Quantum Eraser suggests the concept of retrocausality, which stems ...

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

Quantum mechanics has a way of sounding like pure philosophy until an experiment forces it into everyday language. In 2025, ...
