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…
Thin-film based ultralow noise SQUID magnetometer
M. Schmelz, V. Zakosarenko, A. Chwala +5
We report on the development of an ultralow noise thin-film based SQUID magnetometer. A niobium thin-film pickup coil is connected to the input coil of a SQUID current sensor. The…
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…
Parametric amplification by coupled flux qubits
M. Rehak, P. Neilinger, M. Grajcar +4
We report the parametric amplification of a microwave signal in a Kerr medium formed from superconducting qubits. Two mutually coupled flux qubits, embedded in the current antinode…
Implementation of a Quantum Metamaterial
Pascal Macha, Gregor Oelsner, Jan-Michael Reiner +7
Manipulating the propagation of electromagnetic waves through sub-wavelength sized artificial structures is the core function of metamaterials. Resonant structures, such as split r…
