Turning a quantum battery's environmental sensitivity into an advantage

phys.org · 15mShare

Quantum batteries, devices that store energy by exploiting quantum mechanical phenomena, could, in principle, be charged faster and more efficiently than classical ones. Despite their potential, connecting these batteries to chargers is known to create quantum correlations that can trap some energy inside the combined battery-charger system. This can reduce useful work, or the energy available to complete a task that can be extracted from the battery alone.
