我们介绍了一类新的直流供电单通量量子（SFQ）逻辑，它使用动态（自复位）内部状态来实现完全无时钟的门操作，并提供高免疫力输入数据偏斜。我们称之为DSFQ（动态SFQ）逻辑。我们已经成功地设计和测试了一个2输入DSFQ与门，并表明其能够动态保持其内部状态超过25 ps，同时工作在10 GHz的时钟频率。我们还演示了皮秒级动态DSFQ电路与片上约瑟夫森采样器，只需要低速接口。
We have introduced a new class of dc-powered Single Flux Quantum (SFQ) logic that uses dynamic (self-resetting) internal states to achieve completely clock-free gate operation and provide high immunity to input data skew. We call it DSFQ (dynamic SFQ) logic. We have successfully designed and tested a 2-input DSFQ and gate and showed its ability to hold dynamically its internal states for over 25 ps while operating at 10 GHz clock frequency. We also demonstrated picosecond-scale dynamics of DSFQ circuit with an on-chip Josephson sampler, with only low-speed interfaces required.
