摘要
En 中文
May accepted published A quantum battery is a device where an energy is charged by using a quantum effect. Here, we propose a quantum battery with a charger system composed of N qubits by utilizing a collective effect called a superabsorption. Importantly, the coupling strength between the quantum battery and charger system can be enhanced due to an entanglement. While the charging time scales as Theta(N-1=2) by applying a conventional scheme, we can achieve a charging time Theta(N-1) in our scheme. Our results open the path to ultra-fast charging of a quantum battery.
