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…
On chip synchronization of Bloch oscillations in a strongly coupled pair of small Josephson junctions
Fabian Kaap, David Scheer, Fabian Hassler +1
Bloch oscillations are a fundamental phenomenon linking the adiabatic transport of Cooper pairs to time. Here, we investigate synchronization of the Bloch oscillations in a strongl…
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…
Characterising superconducting filters using residual microwave background
J. S. Lehtinen, E. Mykkänen, A. Kemppinen +3
A normal metal - superconductor hybrid single-electron trap with tunable barrier is utilized as a tool for spectrum analysis at the extremely low signal levels, using only well fil…
Al/AlO/Al-Josephson-junction-based microwave generators for weak-signal applications below 100 mK
Behdad Jalali-Jafari, Sergey V. Lotkhov, Alexander B. Zorin
An application-specific Josephson generator is being developed as an on-chip calibration source for single-microwave-photon detectors operating below 100 mK in the frequen…
Ultra-high-ohmic microstripline resistors for Coulomb blockade devices
Sergey V Lotkhov
In this paper, we report on the fabrication and the low-temperature characterization of extremely high-ohmic microstrip resistors made of a thin film of weakly oxidized titanium. N…
