Many-body enhancement of energy storage in a waveguide-QED quantum battery
Salvatore Tirone, Gian Marcello Andolina, Giuseppe Calajò +2
Quantum batteries have demonstrated remarkable charging properties, showing that a quantum advantage is possible in the realm of quantum thermodynamics. However, finding an effecti…
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…
Optimized QUBO formulation methods for quantum computing
Dario De Santis, Salvatore Tirone, Stefano Marmi +1
Several combinatorial optimization problems can be solved with NISQ devices once that a corresponding quadratic unconstrained binary optimization (QUBO) form is derived. The aim of…
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…
