Abstract(in English) Because of its extremely high energy efficiency, adiabatic quantum-flux-parametron (AQFP) is one of the most promising candidates for the realization of a practical reversible computer. In a previous study, we proposed a logically and physically reversible logic gate using AQFP logic, and numerically demonstrated reversible computing. In the numerical calculation, we assumed that the average energy dissipation at finite temperature corresponds to that at zero temperature. However, how the phase difference of a Josephson junction in AQFP logic behaves at finite temperature is not yet well understood, and whether thermal noise can induce a non-adiabatic state change remains unclear. In the present study, we investigate energy dissipation in AQFP logic at finite temperature through numerical analyses using the Monte Carlo method. We investigate the average and standard deviation of the energy dissipation through both numerical calculation and analytical estimation. Finally, we discuss the minimum energy dissipation required for adiabatic switching operations.
