Quantum batteries could charge extra effectively by skirting typical rules of causality.
Yuanbo Chen on the University of Tokyo and his colleagues analysed whether or not a very counterintuitive quantum phenomenon could play a task in powering quantum batteries – power storage gadgets that could harness quantum results.
In the classical world, causality goes in only one route: if occasion A causes occasion B, then it’s clear that B didn’t additionally trigger A. But on the quantum scale, Chen says that it …
