First formulated in 1935, the famous thought experiment attempts to explain the weirdness of quantum superposition, but a new study shows that this theoretical feline is really only the beginning of ...

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful ...

Modern physics is weird. In quantum mechanics we have the Schrodinger’s cat thought experiment, a cat in a quantum ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...

For the first time, a team of physicists in Austria has carried out an experiment that appears to verify the principle of indefinite causal order: an idea that suggests that timelines of events can ...

More generally, a quantum system can be in a superposition of states, where “state” can refer to other properties, such as the spin of a particle. Much of the Frauchiger-Renner thought experiment ...

(via Sabine Hossenfelder) Physicists have come up with a new experiment to test the quantum twin paradox using a pair of atoms in a superposition. It's an interesting idea because it could tell us ...
