- Abstract:
- Quantum voltage noise source (QVNS) based Johnson noise thermometer (JNT) system employing Josephson junctions (JJs) to generate calculable and quantum accurate pseudo-noise waveform as an artificial noise in measuring the thermodynamic temperature of a resistor. In this paper, we present the progress of design, fabrication, and characterization of the QVNS chip in NIM.
