Influence of device non-uniformities on the accuracy of Coulomb blockade thermometry
Jukka P. Pekola, Eemil Praks, Nikolai Yurttagul +1
We investigate temperature errors of Coulomb blockade thermometer (CBT) arising from inevitable non-uniformities in tunnel junction arrays. The errors are proportional to the junct…
Photonic heat transport in three terminal superconducting circuit
Azat Gubaydullin, George Thomas, Dmitry S. Golubev +3
Quantum heat transport devices are currently intensively studied in theory. Experimental realization of quantum heat transport devices is a challenging task. So far, they have been…
Radio frequency Coulomb blockade thermometry
Florian Blanchet, Yu-Cheng Chang, Bayan Karimi +2
We present a scheme and demonstrate measurements of a Coulomb blockade thermometer (CBT) in a microwave transmission setup. The sensor is embedded in an resonator, where …
A Cooper-Pair Box Coupled to Two Resonators: An Architecture for a Quantum Refrigerator
Andrew Guthrie, Christoforus Dimas Satrya, Yu-Cheng Chang +3
Superconducting circuits present a promising platform with which to realize a quantum refrigerator. Motivated by this, we fabricate and perform spectroscopy of a gated Cooper-pair…
Colloquium: Quantum heat transport in condensed matter systems
Jukka P. Pekola, Bayan Karimi
In this Colloquium recent advances in the field of quantum heat transport are reviewed. This topic has been investigated theoretically for several decades, but only during the past…
Using materials for quasiparticle engineering
Gianluigi Catelani, Jukka P. Pekola
The fundamental excitations in superconductors - Bogoliubov quasiparticles - can be either a resource or a liability in superconducting devices: they are what enables photon detect…
