In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they can occupy several possible states at once, a phenomenon known as ...

Quantum technology has promising potential to revolutionize how large and complex amounts of information are processed. While ...

It looks like time travel, closed timelike curves, quantum mechanics, and quantum entanglement are once again at the centre ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

On a winter day in Wisconsin, you can watch chemistry at work. Road salt and moisture roughen a car’s frame. Steel structures ...
