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…

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…
