- Quantum advantage in charging: superabsorbing quantum batteries can theoretically charge N cells in O(N²) time vs O(N) classical - Dicke quantum battery model (2013) predicted collective charging advantage — experimentally demonstrated in 2023 at small scale - The challenge: maintaining quantum coherence at room temperature long enough to be useful is the fundamental obstacle - Current realistic applications: not consumer electronics, but potentially quantum computing power supplies or precision instruments
