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 ...

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 more than a decade, physicists have argued (and counter-argued) that a subatomic particle can be separated from certain quantum properties, such as its spin—a phenomenon known as the Cheshire cat ...
