绝热量子通量参数（AQFP）逻辑具有最终以几泽焦耳的小能量运行的潜力；然而，这太小了，无法用传统的技术来测量。我们通过将超导谐振器与AQFP栅极耦合来测量如此小的能量耗散，其中由于谐振器的Q因子非常高，插入损耗随小耗散而敏感地变化。我们设计并实现了一个耦合AQFP门的5ghz超导谐振腔。测量结果表明，该栅极在5 GHz工作时的位能接近10 zJ。(C) 2013年美国物理研究所。[http://dx.doi.org/10.1063/1.4790276]
Adiabatic quantum-flux-parametron (AQFP) logic has the potential to operate with an ultimately small bit energy of several zeptojoules; however, this is too small to measure by conventional techniques. We measure such a small energy dissipation by coupling a superconducting resonator with an AQFP gate, where the insertion loss is sensitively varied with the small dissipation due to the very high Q factor of the resonator. We designed and implemented a 5 GHz superconducting resonator coupled with an AQFP gate. Measurement results show that the bit energy of the gate is similar to 10 zJ at 5 GHz operation.
