Fundamentals of quantum thermometry

At this moment the Temperature Unit remains the last, among 7 major units of SI, value that is not regulated at the atomic level. Such state of affairs cannot be deemed adequate for the advanced technology. After implementation of current CODATA “Temperature” redefinition, the next step in provision of scientific support for realizing the Temperature Measurement of new generation seems to be a creation of Quantum Standard on the basis of the fundamental physical constants.
