Quantum physicists have found a way to let a single qubit experience several different “journeys” through time at once, effectively bending a classic limit on how fast quantum systems are allowed to ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed. When you purchase through links on our site, we ...

A proposal for putting a living bacterium into a superposition of quantum states has been unveiled by physicists in the US and China. If successful, the experiment would be the first realization – ...

Quantum mechanics, when examined closely, poses some deep questions about reality. These questions often take the form of thought experiments, which are later (usually much later) followed up by real ...

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is. Researchers recently conducted experiments to answer a decades-old theoretical physics ...

The quantum superposition principle has been tested on a scale as never before in a new study. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition ...

In 1935 Erwin Schrödinger devised his famous thought experiment – in which a cat is both alive and dead at the same time – to highlight the paradoxical nature of quantum mechanics. Now, a group of ...
