Quantum batteries could one day revolutionize energy storage through what seems like a paradox – the bigger the battery, the faster it charges. For the first time, a team of scientists has now demonstrated the quantum mechanical principle of superabsorption that underpins quantum batteries in a proof-of-concept device.
The quirky world of quantum physics is full of phenomena that seem impossible to us. Molecules, for instance, can be become so entwined that they begin acting collectively, and this can lead to a range of quantum effects. That includes superabsorption, which boosts a molecule’s ability to absorb light.
