In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic ...

Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

Until now, creating quantum superpositions of ultra-cold atoms has been a real headache, too slow to be realistic in the laboratory. Researchers at the University of Liège have now developed an ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one.

A NOON state is a superposed quantum state where N particles are in one state "at the same time" and in another "at the same time". Here, the particles are trapped in two wells, within a trap formed ...
