Abstract
The Quantum Roulette Noise Thermometer (QRNT) is a unique type of primary thermometer. Rather than probing a classical thermodynamic variable whose value depends on the average motion of an ensemble of microscopic particles, it makes a series of consecutive measurements of a quantum variable, the flux trapped within a superconducting ring. From the statistical distribution of flux measurements the temperature can be obtained. In principle, the device could operate over a wide range of temperatures, with the upper limit dependent on the superconducting ma- terial chosen for the ring. Its accuracy would be limited by statistical sample size. The QRNT directly addresses the primary objectives of the UK National Measurement System (NMS) Quantum Programme: an NMS based wholly on quantum processes, fundamental constants and the use of portable quantum standards with full primary accuracy. This report reviews preliminary research and assesses the future benefit of QRNT devices to thermal metrology.
