One thing leads to another. It sounds obvious, but in the quantum realm, the saying doesn’t always ring true. A new quantum device can jumble up a sequence of two events so that they take place in ...

Explore the intriguing concepts of superposition and wave/particle duality in quantum physics. Discover what quantum ...

Quantum mechanics attempts to understand how the universe works on an atomic and subatomic level, and so far it turns out ...

The world of quantum mechanics, where particles can be in two places at once or entangled with each other across vast distances, sounds spooky to us living in the macroscopic world of classical ...

The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they ...

PHYSICS HAS A problem. In general relativity, time is entwined with space. It is relative, depending on speed or gravity. In quantum mechanics, however, time is an absolute. It is a smooth background ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...

Why do we not see everyday objects in quantum superpositions? The answer to that long-standing question may partly lie with gravity. So says a group of physicists in Austria, which has shown ...

The question is: is the cat alive or dead? The quantum mechanics answer is: both. That is, there are probabilities associated to each state, depending on the decay rate for the radioactive substance.

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...
