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…
DC measurement of dressed states in a coupled 100~GHz resonator system using a single quasiparticle transistor as a sensitive microwave detector
S. V. Lotkhov, R. Dolata, M. Khabipov
We report on the on-chip detection of microwaves in the frequency range around 100GHz. For the purpose of detection, we employ a discrete transport channel triggered in a supercond…
Traveling-wave parametric amplifier based on three-wave mixing in a Josephson metamaterial
A. B. Zorin, M. Khabipov, J. Dietel +1
We have developed a recently proposed Josephson traveling-wave parametric amplifier with three-wave mixing [A. B. Zorin, Phys. Rev. Applied 6, 034006, 2016]. The amplifier consists…
Flux Dependent Crossover Between Quantum and Classical Behavior in a dc-SQUID
Susanne Butz, Alexey K. Feofanov, Kirill G. Fedorov +7
In a coupled system of one classical and one quantum mechanical degree of freedom, the quantum degree of freedom can facilitate the escape of the whole system. Such unusual escape…
