Published purpose

The Project will develop and test a new primary cryogenic temperature sensor, and compare it with NRC thermometry standards. The primary cryogenic temperature sensor, thermometer, under consideration is called a “quantum-correlation thermometer” because it compares temperaturedependent thermomechanical noise with temperature-independent quantum noise. This allows it to be a primary, or “self-calibrating”, noise thermometer. This concept has only been demonstrated down to 10 K, and hasn’t been compared with international temperature scale standards. The Project results may find application in any quantum R&D performed below 1 K, and lead towards commercial development of a quantum-correlation thermometer. Success of the Project could lead to a follow-up project with one or more Canadian SMEs and a path towards commercialization.
