Cooper-pair splitters as circuit elements for realizing topological superconductors
Guilherme Delfino, Dmitry Green, Saulius VaitiekÄnas +2
Advances in materials and fabrication of superconducting devices allows the exploration of novel quantum effects in synthetic superconducting systems beyond conventional Josephson…
Percolative supercurrent in superconductor-ferromagnetic insulator bilayers
A. Maiani, A. C. C. Drachmann, L. Galletti +4
We report tunneling spectroscopy and transport measurements in superconducting Al and ferromagnetic-insulator EuS bilayers. The samples display remanent spin-splitting, roughly hal…
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…
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…
