In the world of quantum physics, another record appears to have just been broken. In a paper listed on the preprint site ArXiv, researchers at the University of Science and Technology of China claim to have observed atoms in a state of quantum superposition for 23 minutes. Being able to keep quantum states stable for such a long time could help make quantum devices more durable and discover strange new effects in quantum physics, they argue.
Superposition is a phenomenon where an object at a given moment has the potential to occupy multiple different states, but the object’s actual state is unknown. Very small
