Quantum Battery Breakthrough: One-Minute Charge Could Power Devices for Years
Scientists unveiled the first working quantum battery: a laser-charged prototype that stores energy via quantum effects and remains charged far longer than its charging time, though the device is currently tiny and discharges in nanoseconds. The team envisions scaling up so a minute of charging could yield years of power, potentially enabling contactless drone charging and applications in quantum computing, but consumer‑grade batteries are still years away.
