A quantum battery is a type of electric battery that utilizes the principles of quantum mechanics to store energy. They have the potential to be much more efficient and powerful than traditional batteries.

Quantum batteries are still in the early stages of development.^[1]

The concept of quantum batteries was first proposed in the early 1990s by a team of researchers at the University of California, Berkeley.^[2] The researchers showed that it was possible to store energy in the quantum states of atoms and molecules. However, it was not until the early 2000s that the first quantum batteries were actually built.
