Basic cell for a quantum microwave router
Evgeniya Mutsenik, Aidar Sultanov, Leonie Kaczmarek +4
We report the first experimental realization of a scalable basic cell for quantum routing, enabling coherent control and exchange of microwave photons between two spatially separat…
Measuring coherent dynamics of a superconducting qubit in an open waveguide
Aidar Sultanov, Evgeniya Mutsenik, Matthias Schmelz +5
We measured the relaxation and decoherence rates of a superconducting transmon qubit in a resonator-free setting. In our experiments, the qubit is coupled to an open coplanar waveg…
Influence of mechanical deformations on the performance of a coaxial shield for a cryogenic current comparator
Nicolas Marsic, Wolfgang F. O. Müller, Volker Tympel +10
This paper studies the impact of mechanical deformations on the performance of a coaxial-type cryogenic current comparator (CCC). Such deformations may become a concern as the size…
Numerical analysis of a folded superconducting coaxial shield for cryogenic current comparators
Nicolas Marsic, Wolfgang F. O. Müller, Herbert De Gersem +6
This paper presents a new shield configuration for cryogenic current comparators (CCCs), namely the folded coaxial geometry. An analytical model describing its shielding performanc…
Reflection-enhanced gain in traveling-wave parametric amplifiers
S. Kern, P. Neilinger, E. Iľichev +12
The operating principle of traveling-wave parametric amplifiers is typically understood in terms of the standard coupled mode theory, which describes the evolution of forward propa…
A new family of field-stable and highly sensitive SQUID current sensors based on sub-micrometer cross-type Josephson junctions
M. Schmelz, V. Zakosarenko, T. Schönau +5
We report on the development of a new family of SQUID current sensors based on sub-micron cross-type Josephson tunnel junctions. Their low total junction capacitance permit high us…
Nearly quantum limited nanoSQUIDs based on cross-type Nb/AlOx/Nb junctions
M. Schmelz, V. Zakosarenko, T. Schönau +4
We report on the development of nearly quantum limited SQUIDs with miniature pickup loop dimensions. The implemented high quality and low capacitance cross-type Nb/AlOx/Nb Josephso…
Detection of weak microwave fields with an underdamped Josephson junction
G. Oelsner, C. K. Andersen, M. Rehák +6
We have constructed a microwave detector based on the voltage switching of an underdamped Josephson junction, that is positioned at a current antinode of a λ/4 coplanar waveguide r…
Investigation of all niobium Nano-SQUIDs based on sub-micrometer cross-type Josephson junctions
M. Schmelz, Y. Matsui, R. Stolz +6
We report on the development of highly sensitive SQUIDs featuring sub-micrometer loop dimensions. The integration of high quality and low capacitance SIS Nb/AlOx/Nb cross-type Jose…
