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…
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…
Photon-activated electron hopping in a single-electron trap enhanced by Josephson radiation
Servey V. Lotkhov, Behdad Jalali-Jafari, Alexander B. Zorin
Using a Josephson junction interferometer (DC SQUID) as a microwave source for irradiating a single-electron trap, both devices fabricated on the same chip, we study the process of…
Nanoscale multifunctional sensor formed by a Ni nanotube and a scanning Nb nanoSQUID
J. Nagel, A. Buchter, F. Xue +14
Nanoscale magnets might form the building blocks of next generation memories. To explore their functionality, magnetic sensing at the nanoscale is key. We present a multifunctional…
