Even if it turns out that time loops never take shape, studying them provides key insights into the deepest rules of reality.

Input/output is the term for time before and after a particular physical moment or scenario, and in certain quantum scenarios, those ‘befores’ and ‘afters’ can be interchangeable. Researchers have ...

A team of Australian and international scientists has, for the first time, created a full picture of how errors unfold over ...

In the world of quantum physics, the rules that govern reality behave in ways that challenge what we think we know. Particles can be in two places at once. Actions on one particle can instantly affect ...

Quantum effects are no longer confined to ultra-cold chips and vacuum chambers. For the first time, researchers have deliberately engineered a controllable quantum bit inside living cells and tied it ...

Quantum communication saw major progress, including longer-distance demonstrations and systems that operate closer to ...

The true danger isn't just that quantum computers will read our emails. It's that they'll fundamentally change what's ...
