Quantum batteries could charge better by breaking rules of causality

Quantum batteries may cost extra effectively by skirting standard guidelines of causality.

Yuanbo Chen on the College of Tokyo and his colleagues analysed whether or not a very counterintuitive quantum phenomenon may play a task in powering quantum batteries – power storage gadgets that would harness quantum results.

Within the classical world, causality goes in only one course: if occasion A causes occasion B, then it’s clear that B didn’t additionally trigger A. However on the quantum scale, Chen says that it …
