AbstractWe describe our progress towards a high-precision measurement of temperature using Johnson noise. Using a Quantized Voltage Noise Source (QVNS) based on the Josephson effect as a calibrated noise source, we have been able to measure the gallium and water triple point temperatures with an accuracy approaching 100 ppm.
