Quantum physics

Physicists are trying to rewrite the axioms of quantum theory from scratch in an effort to understand what it all means. The problem? They’ve been almost too successful.

Time isn’t just another dimension, argues Tim Maudlin. To make his case, he’s had to reinvent geometry.

Physicists are attempting to map the distribution of the prime numbers to the energy levels of a particular quantum system.

In order to fully understand the quantum world, we may have to develop a new realm of mathematics.

A simple analogue could offer insights into one of the most astonishing results of quantum mechanics.

A new class of quantum particle is about to emerge from the tangled considerations of quantum statistics.

Can balloon animals help blunt uneasy feelings about “spooky action at a distance”?

Physicists are closing the door on an intriguing loophole around the quantum phenomenon Einstein called “spooky action at a distance.”

A new theory explains how fragile quantum states may be able to exist for hours or even days in our warm, wet brain. Experiments should soon test the idea.
