A quantum battery is a device that stores energy in the quantum states of particles. In the new work, the battery was modeled as a pair of qubits — the tiniest carriers of information that can be in a "zero" state, a "one" state, or a mixture of both.

A massive star ends its life in a spectacular collapse: the core compresses into a neutron star or a black hole, while the outer layers fly off in a dazzling supernova.
