Quantum batteries have theoretically exciting properties da-kuk/Getty Images
Hooking up a quantum computer to a quantum battery could make it much more energy-efficient and enable machines to pack more processing power into the same physical space.
Quantum batteries, like regular batteries, can store energy to provide power, but rather than using electrochemical reactions, they are built from quantum bits, or qubits, that can extract energy from quantum processes, like entanglement. While they have the advantage of charging much faster than regular devices, researchers have struggled to build working examples or find practical uses for them.
