Quantum voltage noise source (QVNS). This device provides a fundamentally accurate voltage signal that can be compared to the voltage noise from electrons in a resistor. Measuring the voltage noise enables researchers to determine the Boltzmann constant, which relates an energy of a system to its temperature. This research was carried out at the Physical Measurement Laboratory (PML) of the National Institute of Standards and Technology (NIST). Image published in 2017. | |
