An rf-SQUID-based traveling-wave parametric amplifier with -84 dBm input saturation power across more than one octave bandwidth
Victor Gaydamachenko, Christoph Kissling, Lukas Grünhaupt
Traveling-wave parametric amplifiers (TWPAs) have become an essential tool for the readout of quantum circuits and the search for dark matter. We report on the implementation of an…
Demonstration of dual Shapiro steps in small Josephson junctions
Fabian Kaap, Christoph Kissling, Victor Gaydamachenko +2
Bloch oscillations in small Josephson junctions were predicted theoretically as the quantum dual to Josephson oscillations. A significant consequence of this prediction is the emer…
Vulnerability to Parameter Spread in Josephson Traveling-Wave Parametric Amplifiers
Christoph Kissling, Victor Gaydamachenko, Fabian Kaap +4
We analyze the effect of circuit parameter variation on the performance of Josephson traveling-wave parametric amplifiers (JTWPAs). Specifically, the JTWPA concept we investigate i…
Numerical analysis of a three-wave-mixing Josephson traveling-wave parametric amplifier with engineered dispersion loadings
Victor Gaydamachenko, Christoph Kissling, Ralf Dolata +1
The recently proposed Josephson traveling-wave parametric amplifier (JTWPA) based on a ladder transmission line consisting of radio-frequency SQUIDs and exploiting three-wave mixin…
Superconducting microwave resonators with non-centrosymmetric nonlinearity
M. Khabipov, V. Gaydamachenko, C. Kissling +2
We investigated both theoretically and experimentally open-ended coplanar waveguide resonators with rf SQUIDs embedded in the central conductor at different positions. These rf SQU…
