Abstract :
We tried a direct comparison between a 1-V NbN-based programmable superconductor-normal metal-superconductor (SNS) Josephson array and a conventional superconductor-insulator-superconductor (SIS) Josephson array. In preliminary experiment the voltage difference of the two arrays was -4.3 times 10-9 V in average of 10 measurement sets. The deviation is resulted from the fluctuations of the background in the measurement set
