Physicists have created a Schrödinger's cat state at unusually hot temperatures, and it could be a major step toward the development of practical quantum computers. Schrödinger's cat states exist in ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

Where do you see patterns in chaos? It has now been demonstrated in the incredibly tiny quantum realm. Researchers detail an experiment that confirms a theory first put forth 40 years ago stating that ...

In the everyday world that humans experience, objects behave in a predictable way, explained by classical physics. One of the important aspects of classical physics is that nothing, not even ...

Does quantum physics place limits on the extent to which we have free will? This long-debated question stems from the way different physicists interpret the mathematics of quantum theory, but now ...

Are quantum particles polygamous? New experiments suggest some of them abandon long-standing partnerships when ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...
