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…
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…
Accelerating dark-matter axion searches with quantum measurement technology
Huaixiu Zheng, Matti Silveri, R. T. Brierley +2
The axion particle, a consequence of an elegant hypothesis that resolves the strong-CP problem of quantum chromodynamics, is a plausible origin for cosmological dark matter. In sea…
Stückelberg interference in a superconducting qubit under periodic latching modulation
M. P. Silveri, K. S. Kumar, J. Tuorila +4
When the level separation of a qubit is modulated periodically across an avoided crossing, tunneling to the excited state - and consequently Landau-Zener-Stückelberg interference -…
Hard domain walls in superfluid 3He-B
Matti Silveri, Tero Turunen, Erkki Thuneberg
We study theoretically planar interfaces between two domains of superfluid 3He-B. The structure of the B-B walls is determined on the scale of the superfluid condensation energy, a…
