First quantum battery developed and tested by Australian researchers

It doesn't delve into what quantum battery are, unfortunately, other than saying they "leverage properties of quantum mechanics” and "charge faster as they get large" — I'm curious about the practical implications of the latter, should the technology become ubiquitous. Still, quite interesting.

It’s written in the linked paper:

> Here, we utilise a microcavity quantum battery as an experimental platform that superextensively captures light energy and converts it to an electric current via the incorporation of charge transport layers into the resonant microcavity. This architecture enables, for the first time, a complete quantum battery charge-discharge cycle. We demonstrate that strong light–matter coupling induced by the microcavity leads to superextensive scaling of the steady-state electrical discharging power under low-intensity, incoherent illumination. Our results provide the first experimental demonstration of superextensive light-to-charge conversion in steady-state, highlighting the feasibility of leveraging strong light–matter coupling for enhanced energy harvesting under low-light conditions.

Ohhh, I assumed a paywall. Thank you! What a thoroughly interesting reading that was! Poor Einstein would find all of it preposterous.
