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 ...

Red and blue: a photon of two colours has been made. (Courtesy: iStock/-strizh-) Individual photons have been put into a quantum superposition of two different colours by a team of physicists in the ...

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 – ...
