Quantum work extraction efficiency for noisy quantum batteries: the role of coherence
Salvatore Tirone, Raffaele Salvia, Stefano Chessa +1
Quantum work capacitances and maximal asymptotic work/energy ratios are figures of merit characterizing the robustness against noise of work extraction processes in quantum batteri…

Universal framework for simultaneous tomography of quantum states and SPAM noise
Abhijith Jayakumar, Stefano Chessa, Carleton Coffrin +3
We present a general denoising algorithm for performing simultaneous tomography of quantum states and measurement noise. This algorithm allows us to fully characterize state prepar…

Quantum Work Capacitances: ultimate limits for energy extraction on noisy quantum batteries
Salvatore Tirone, Raffaele Salvia, Stefano Chessa +1
We present a theoretical analysis of the energy recovery efficiency for quantum batteries composed of many identical quantum cells undergoing noise. While the possibility of using…
