Comment on Quantum battery upends the rules of charging

Comments

I feel like (as is usual with nontechnical reporting on cutting edge science) this article isn't doing a great job at communicating the underlying tech well here. Had to independently look up some descriptions of what super absorption is, and what actually makes it a quantum effect.

Sounds like the idea is, if you've got a bunch of light emitters spaced far closer to each other than the wavelength of light they are emitting, the light output becomes quadratic on the number of emitters. as opposed to linear on the number of emitters in the standard case. And the reverse becomes true as well.

Based on that, I'm pessimistic on the potential of this, as it sounds like charging requires a conversion from electricity to light, and then discharging would also be a conversion from light back to electricity, and we don't exactly have the most lossless processes for that conversion.

Maybe useful in certain kinds of optics or laser work though, where directly dumping the stored energy as light would be desired?

My reading between the lines of the article is that the application would likely be in quantum computing circuits. Where it can be tricky to deliver and store power because everything is supercomputing icebergs.

But I agree, this article is trash. This is simply very bad journalism.
