SC-1 Etching of Niobium and Titanium Nitride Thin Films
Adrián Gutiérrez-Cruz, K. A. C. Rathnathilaka, Jani M. Taskinen +6
Dry etching techniques, ubiquitous in microelectronics fabrication, often result in challenging levels of undesired collateral plasma-induced damage. In this work, we demonstrate a…
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…
Thermal spectrometer for superconducting circuits
Christoforus Dimas Satrya, Yu-Cheng Chang, Aleksandr S. Strelnikov +5
Superconducting circuits provide a versatile and controllable platform for studies of fundamental quantum phenomena as well as for quantum technology applications. A conventional t…
