Cryogenic sensor enabling broad-band and traceable power measurements
J. -P. Girard, R. E. Lake, W. Liu +4
Recently, great progress has been made in the field of ultrasensitive microwave detectors, reaching even the threshold for utilization in circuit quantum electrodynamics. However,…
Bolometer operating at the threshold for circuit quantum electrodynamics
R. Kokkoniemi, J. -P. Girard, D. Hazra +7
Radiation sensors based on the heating effect of the absorbed radiation are typically relatively simple to operate and flexible in terms of the input frequency. Consequently, they…
Optimized heat transfer at exceptional points in quantum circuits
Matti Partanen, Jan Goetz, Kuan Yen Tan +12
Superconducting quantum circuits are potential candidates to realize a large-scale quantum computer. The envisioned large density of integrated components, however, requires a prop…
Observation of a broadband Lamb shift in an engineered quantum system
Matti Silveri, Shumpei Masuda, Vasilii Sevriuk +9
The shift of energy levels owing to broadband electromagnetic vacuum fluctuations, the Lamb shift, has been pivotal in the development of quantum electrodynamics and in understandi…
Flux-tunable heat sink for quantum electric circuits
Matti Partanen, Kuan Yen Tan, Shumpei Masuda +10
Superconducting microwave circuits show great potential for practical quantum technological applications such as quantum information processing. However, fast and on-demand initial…
Cryogenic microwave source based on nanoscale tunnel junctions
Shumpei Masuda, Kuan Y. Tan, Matti Partanen +5
We experimentally realize an incoherent microwave source driven by voltage-controlled quantum tunneling of electrons through nanoscale normal-metal--insulator--superconductor junct…
