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…
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 Algorithms for the computation of quantum thermal averages at work
Riccardo Aiudi, Claudio Bonanno, Claudio Bonati +6
Recently, a variety of quantum algorithms have been devised to estimate thermal averages on a genuine quantum processor. In this paper, we consider the practical implementation of…
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…
Work extraction processes from noisy quantum batteries: the role of non local resources
Salvatore Tirone, Raffaele Salvia, Stefano Chessa +1
We demonstrate an asymmetry between the beneficial effects one can obtain using non-local operations and non-local states to mitigate the detrimental effects of environmental noise…
