In the classical world, if you tried to charge a battery using two chargers, you would have to do so in sequence, limiting the available options to just two possible orders. However, leveraging the ...

The original version of this story appeared in Quanta Magazine. For the past few decades, researchers have understood that quantum computers should eventually be able to crack the widely used codes ...

Quantum computers could gain an advantage over their conventional counterparts by bypassing the usual rules of cause and effect. “We were curious about how to push the limits of quantum computers, ...

Causality is key to our experience of reality: dropping a glass, for example, causes it to smash, so it can’t smash before it’s dropped. But in the quantum world those rules don’t necessarily apply, ...

Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve some problems. A new preprint study shows how ...

For just over a decade, physicists have been studying a strange phenomenon in the quantum world. At very small scales, it seems that the temporal order of different events may not always be ...

From subatomic particles to complex molecules, quantum systems hold the key to understanding how the universe works. But there's a catch: when you try to model these systems, that complexity quickly ...

You drop a cup and it smashes. I flick a light switch and the bulb glows. Effect follows cause – it is a hard-and-fast rule of the universe. Except, perhaps, at a fundamental level. Because when we ...

For the first time, a team of physicists in Austria has carried out an experiment that appears to verify the principle of indefinite causal order: an idea that suggests that timelines of events can ...

(Nanowerk News) Batteries that exploit quantum phenomena to gain, distribute and store power promise to surpass the abilities and usefulness of conventional chemical batteries in certain low-power ...
