For faster battery charging, try a quantum battery?

(Phys.org)—Physicists have shown that a quantum battery—basically, a quantum system such as a qubit that stores energy in its quantum states—can theoretically be charged at a faster rate than conventional batteries. This "quantum speedup" arises from quantum entanglement among multiple qubits, which essentially provides a shortcut between the qubits' uncharged and charged states, allowing for faster charging.
