Abstract :
A novel form of primary thermometer called the quantum roulette noise thermometer (QRNT), based on flux quantisation in a HTS superconducting ring, has been proposed. The basis of the QRNT is that the flux state of a SQUID ring is allowed to evolve freely. The flux state is repeatedly interrogated to establish a probability distribution from which the temperature of the device is derived.
