Strike a gong and the sound fades in layers: the low hum lingers longer, the high overtones vanish first, leaving silence behind. So too a qubit, living its quantum life, leaves not one but three echoes of its own past.

In quantum batteries, charging can be accelerated by shuffling the steps in time, like a deck of cards. Instead of a smooth energy climb, you get abrupt efficiency explosions, like microscopic supernovae inside atoms.
