Its intrinsic switching time is very short ; on the order of a picosecond . perhaps even more important is the low power dissipation ; superconducting circuits dissipate on the order of a microwatt per gate , a thousand times less than cmos circuits 这种数字电子技术具有高速、低功耗的特点，使用基于rsfq技术的逻辑电路的时钟频率可达到几百个ghz ，而功耗只有0 . 3微瓦门。
