Harnessing Nth Root Gates for Energy Storage
arXiv:2409.10345 · doi:10.3390/e26110952
Abstract
We explore the use of fractional control-not gates in quantum thermodynamics. The Nth-root gate allows for a paced application of two-qubit operations. We apply it in quantum thermodynamic protocols for charging a quantum battery. Circuits for three (and two) qubits are analysed by considering the generated ergotropy and other measures of performance. We also perform an optimisation of initial system parameters, e.g. initial quantum coherence of one of the qubits affects strongly the efficiency of protocols and the system's performance as a battery. Finally, we briefly discuss the feasibility for an experimental realisation.
