The development of quantum batteries paves the way for instant recharging.
Quantum batteries make use of the same quantum mechanics properties that enable next-generation quantum computers.
A group of South Korean researchers has already calculated that quantum battery technology could reduce electric car charging times from 10 hours to three minutes.
A micromaser has been described as an excellent quantum battery model.
It employs an electromagnetic field to store energy charged through a stream of qubits while also protecting against overcharging.
Although a fully functional quantum battery prototype is still a long way off, a proof-of-concept device for charging quantum batteries with lasers has already been demonstrated.
