| Zusammenfassung | A direct comparison of two voltages at 0.6 V reproduced by programmable arrays with Nb/Al/AlOx/Al/AlOx/Al/Nb Josephson junctions was carried out using a SQUID as a null-detector. The voltage difference was measured and found to be smaller than 1.2 × 10-17 V. Jumps of the current in the flux transformer loop can be attributed to phase slipping events when the phase lock in the arrays is broken. |
