Abstract
A Coulomb-blockade thermometer (CBT) provides calibration-free measurement of low temperatures, even in strong magnetic fields---but slowly. A standard conductance measurement with a CBT takes typically minutes, which is useless in applications where relatively fast changes in temperature are monitored. Besides, a slow measurement is prone to drifts, and low-frequency noise. The authors solve this issue by hooking a CBT sensor into a radio-frequency tank circuit, making the measurement about 1000 times faster. Their approach is expected to impact low-temperature thermometry, for $e.g.$ applications in quantum technology.
