Initial experimental results on a superconducting-qubit reset based on photon-assisted quasiparticle tunneling
V. A. Sevriuk, W. Liu, J. Rönkkö +15
We present here our recent results on qubit reset scheme based on a quantum-circuit refrigerator (QCR). In particular, we use the photon-assisted quasiparticle tunneling through a…
Charge dynamics in quantum-circuit refrigeration: thermalization and microwave gain
Hao Hsu, Matti Silveri, Vasilii Sevriuk +2
Previous studies of photon-assisted tunneling through normal-metal-insulator-superconductor junctions have exhibited potential for providing a convenient tool to control the dissip…
Superconducting charge sensor coupled to an electron layer in silicon
Máté Jenei, Ruichen Zhao, Kuan Y. Tan +8
Schemes aimed at transferring individual electrons in semiconductor devices and detecting possible transfer errors have increasing importance for metrological applications. We stud…
Waiting time distributions in a two-level fluctuator coupled to a superconducting charge detector
Máté Jenei, Elina Potanina, Ruichen Zhao +7
We analyze charge fluctuations in a parasitic state strongly coupled to a superconducting Josephson-junction-based charge detector. The charge dynamics of the state resembles that…
Fast control of dissipation in a superconducting resonator
Vasilii Sevriuk, Kuan Yen Tan, Eric Hyyppä +8
We report on fast tunability of an electromagnetic environment coupled to a superconducting coplanar waveguide resonator. Namely, we utilize a recently-developed quantum-circuit re…
Calibration of cryogenic amplification chains using normal-metal--insulator--superconductor junctions
Eric Hyyppä, Máté Jenei, Shumpei Masuda +7
Various applications of quantum devices call for an accurate calibration of cryogenic amplification chains. To this end, we present a convenient calibration scheme and use it to ac…
