Otto refrigerator based on a superconducting qubit: classical and quantum performance
B. Karimi, J. P. Pekola
We analyse a quantum Otto refrigerator based on a superconducting qubit coupled to two LC-resonators each including a resistor acting as a reservoir. We find various operation regi…
Thermal conductance of Nb thin films at sub-kelvin temperatures
A. V. Feshchenko, O. -P. Saira, J. T. Peltonen +1
We determine the thermal conductance of thin niobium (Nb) wires on a silica substrate in the temperature range of 0.1 - 0.6 K using electron thermometry based on normal metal-insul…
High-performance electronic cooling with superconducting tunnel junctions
H Courtois, Hung Q. Nguyen, Clemens Winkelmann +1
When biased at a voltage just below a superconductor's energy gap, a tunnel junction between this superconductor and a normal metal cools the latter. While the study of such device…
