| Title: |
Demonstration chip for measuring ac quantum voltage waveforms |
| Description: |
(1996) Laying the groundwork to produce highly accurate ac voltages, NIST researchers used this circuit with 512 Josephson junctions to measure the first quantized voltage steps produced with a pulse-driven waveform. The junctions are made of niobium electrodes with gold-palladium alloy barriers.
*PML, circuit, voltage, niobium
