Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is.

Can a single particle have a temperature? It may seem impossible with our standard understanding of temperature, but columnist Jacklin Kwan finds that it’s not exactly ruled out in the quantum realm ...

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 ...

Essentially, the quantum metric creates a “geometric” drag on the electrons. When the magnetic field is applied, it breaks ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

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

Laurent Simons, a Belgian prodigy, earned his PhD in quantum physics at 15 and is now pursuing a second PhD in AI-powered ...

Quantum computing is nearing the point of practical use, but scientists still need to make some specific breakthroughs.

Whether she is walking a fashion runway, amping herself up at the top of a mountain or digging into one of those physics lessons she takes "for fun," Olympic champion Eileen Gu can probably boil down ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has ...
