Scientists have found a way to charge a quantum battery in a fraction of a second by illuminating it with special light. Two-photon pumping creates 'squeezed light' that locks energy inside, preventing it from dissipating. Such batteries could become the basis for powerful quantum devices of the future.
🎯 Squeezed light, which locks in charge, already helps physicists catch gravitational waves—it boosts measurement precision in detectors like LIGO, enabling them to pick up vibrations a quintillion times smaller than an atom.
