Electronic primary thermometry -- experimental comparison of the Coulomb Blockade and Shot Noise Thermometer
Eemil Praks, Libin Wang, Yu-Cheng Chang +4
Since the redefinition of the kelvin in 2019, new methods of primary thermometry have been considered to replace the currently agreed temperature scale in the very high and low tem…
Revisiting dissipation-driven phase transition in a Josephson junction
Diego Subero, Yu-Cheng Chang, Miguel Monteiro +2
Despite extensive experimental and theoretical work over several decades, Schmid-Bulgadaev quantum phase transition remains a subject of debate. Here we revisit this problem by per…
Heat measurement of quantum interference
Christoforus Dimas Satrya, Aleksandr S. Strelnikov, Luca Magazzù +5
Coherence is a key property of quantum systems, and it plays a central role in the operation and performance of quantum heat engines and refrigerators. Despite its importance for t…
Strong-coupling quantum thermodynamics using a superconducting flux qubit
Rishabh Upadhyay, Bayan Karimi, Diego Subero +4
Thermodynamics in quantum circuits aims to find improved functionalities of thermal machines, highlight fundamental phenomena peculiar to quantum nature in thermodynamics, and poin…
Probing strongly driven and strongly coupled superconducting qubit-resonator system
Oleh V. Ivakhnenko, Christoforus Dimas Satrya, Yu-Cheng Chang +5
We investigated a strongly driven qubit strongly connected to a quantum resonator. The measured system was a superconducting flux qubit coupled to a coplanar-waveguide resonator wh…
Quantum-Ready Microwave Detection with Scalable Graphene Bolometers in the Strong Localization Regime
Yu-Cheng Chang, Federico Chianese, Naveen Shetty +8
Exploiting quantum interference of charge carriers, epitaxial graphene grown on silicon carbide emerges as a game-changing platform for ultra-sensitive bolometric sensing, featurin…
