Boffins create key tech for quantum batteries

Potentially live and flat at the same time

A team of boffins have demonstrated the quantum mechanical principle of super-absorption that underpins quantum batteries in a proof-of-concept device.

Lead boffin on the project James Quach said that super-absorption was a quantum collective effect where transitions between the states of the molecules interfere constructively.

"Constructive interference occurs in all kinds of waves (light, sound, waves on water), and occurs when different waves add up to give a larger effect than either wave on its own. Crucially this allows the combined molecules to absorb light more efficiently than if each molecule were acting individually."

The idea is really important if you are trying to build a quantum battery as the more energy-storing molecules you have, the more efficiently they'll be able to absorb that energy.

Ironically it means that the bigger you make the battery, the faster it will charge.
