From two dimensions to wire networks in a dice-lattice Josephson array
J. D. Bondar, L. Banszerus, W. Marshall +5
We investigate Josephson arrays consisting of a dice-lattice network of superconducting weak links surrounding rhombic plaquettes of proximitized semiconductor. Josephson coupling…
Cooper-pair splitters as circuit elements for realizing topological superconductors
Guilherme Delfino, Dmitry Green, Saulius Vaitiekėnas +2
Advances in materials and fabrication of superconducting devices allows the exploration of novel quantum effects in synthetic superconducting systems beyond conventional Josephson…
The hybrid Josephson rhombus: A superconducting element with tailored current-phase relation
L. Banszerus, C. W. Andersson, W. Marshall +4
Controlling the current-phase relation (CPR) of Josephson elements is essential for tailoring the eigenstates of superconducting qubits, tuning the properties of parametric amplifi…
Bolometric detection of Josephson radiation
Bayan Karimi, Gorm Ole Steffensen, Andrew P. Higginbotham +3
A Josephson junction (JJ) has been under intensive study ever since 1960's. Yet even in the present era of building quantum information processing devices based on many JJs, open q…
Voltage-controlled synthesis of higher harmonics in hybrid Josephson junction circuits
L. Banszerus, W. Marshall, C. W. Andersson +4
We report measurements of the current-phase relation of two voltage-controlled semiconductor-superconductor hybrid Josephson junctions (JJs) in series. The two hybrid junctions beh…
