A group of researchers led by Andreas Wallraff, Professor of Solid State Physics at ETH Zurich, has performed a loophole-free Bell test to disprove the concept of "local causality" formulated by ...

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, ...

(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 ...

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 ...

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 ...

Bell's theorem, the well-known theoretical framework introduced by John Bell decades ago, delineates the limits of classical physical processes arising from relativistic causality principles. These ...

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, ...

(via Sabine Hossenfelder) To us normal people, cause and effect are linked together in a distinct order. The cause occurs first, and the effect follows after. But according to a new paper, that causal ...

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 ...

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 ...
