Scientists from the universities of Alberta and Toronto developed a blueprint for a new quantum battery that doesn't leak charge.

"A quantum is a tiny, nano-size battery meant to be used for applications on the nano scale," explained U of A chemist Gabriel Hanna, who was principal investigator on the study.

He said the research provides a theoretical demonstration that creating a loss-free is possible—offering an advantage over previously proposed quantum batteries.

"The batteries that we are more familiar with—like the that powers your smartphone—rely on classical electrochemical principles, whereas quantum batteries rely solely on ," Hanna noted.

He said the batteries may become an important component in many quantum devices—able to power quantum computers, for example—and in practice, they could be built using current solid-state technologies.
