Electrical Drive of a Josephson Junction Array using a Cryogenic BiCMOS Pulse Pattern Generator: Towards a Fully Integrated Josephson Arbitrary Waveform Synthesizer
Yerzhan Kudabay, Oliver Kieler, Michael Starkloff +5
We combine a cryogenic BiCMOS integrated circuit, which generates high-speed return-to-zero (RTZ) pulses, with a superconducting Josephson junction array. The BiCMOS circuit acts a…
Fast optical data transfer into a Josephson junction array
K. Kohopää, J. Nissilä, E. Mykkänen +19
We employ externally shunted Nb-AlO-Nb Josephson junctions for demonstrating a circuit that is suitable for an optically driven Josephson Arbitrary Waveform Synthesizer (JAWS).…
In-situ electro-optic sampling of microwave signals under cryogenic conditions and for superconducting applications
Shekhar Priyadarshi, Rinis Ferizaj, Oliver Kieler +8
We demonstrate a cryogenic electro-optic sampling (EOS) setup that allows for the measurement of microwave signals at arbitrary positions on a cryogenic chip-scale device. We use a…
Influence of the magneto-volume effect on the transient reflectivity of MnSi
J. Kalin, S. Sievers, H. Füser +4
The magneto-volume effect is a well-established yet frequently overlooked phenomenon in magnetic materials that may affect a wide range of physical properties. Our study explores t…
