| Abstract(in English) | Superconducting digital devices are promising candidates to realize a exascle computer since their power consumption is at least 1000 times smaller than that of CMOS. Recently, novel superconducting devices, whose power consumption is even smaller than that of rapid single-flux-quantum (RSFQ) circuits, have been investigated, thereby further increasing their advantages on power consumption. We have been studying adiabatic quantum-flux-parametron (AQFP) circuits whose power consumption is approximately 100 times smaller than that of RSFQ circuits. However, it is quite difficult to experimentally evaluate such small power consumption because in general a large number of gates wre needed for such eveluation. Therefore, we propose a novel method to evaluate extremely small power consumption using a superconducting resonator with a very high Q factor, where we calculate power consumption using the decrease of the Q factor. By using this method, measurement results show that power consumption of an AQFP gate is ～10^<-10>W, which corresponds to energy dissipation of ～10^<-20>J per switch. These results prove that AQFP circuits works with extremely small power. |
