Space and time looked settled, at least in broad outline. Einstein’s special relativity gave physics a durable framework for ...

Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to test the ...

To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.

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 ...

Scientists measured light particles spending a negative amount of time inside a cloud of atoms, that appeared to exit the ...

Quantum batteries could charge more efficiently by skirting conventional rules of causality. Yuanbo Chen at the University of Tokyo and his colleagues analysed whether a particularly counterintuitive ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

Batteries could charge up by relying on a quantum effect known as indefinite causal order, whereby the laws of cause and effect are scrambled and power can move through the system quicker. When you ...

Classical physics presumes a fixed order of events: causes precede effects along a well‐defined temporal axis. Quantum mechanics, however, permits scenarios in which the causal order of operations ...

(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 ...
