What Is a Quantum Battery? And When Will It Power My Laptop?

The modern battery has come a long way in its 224-year history. In the place of Alessandro Volta’s piles of metal disks and brine-soaked cloth, we now have batteries the dimensions of a graham cracker that can last days before needing a recharge.

“Therefore it seems natural to seek thermodynamic quantum advantages in quantum systems that are driven out of equilibrium.” The group went on to note that quantum entanglement is linked with how fast energy can be stored in many-body quantum systems, a discovery that has prompted research into quantum systems as energy storage devices.
