WebJosephson junctions drive the operation of superconducting qubits and they are the key for the coupling and the interfacing of superconducting qubit components with other quantum platforms. They are the only means to introduce non linearity in a superconducting circuit and offer direct solutions to tune the properties of a superconducting qubit, thus enlarging …
WebOur results for Nb/Ni/Nb junctions are in good agreement with recent experimental studies. Our approach combines density functional theory and Bogoliubov-de Gennes model and opens a path for material composition optimization in magnetic Josephson junctions and superconducting magnetic spin valves. WebSpin-filter Josephson Junction Most prefered material for spin current generation from spin imbalance in the band structure can be in a spin filter with a high spin filter efficiency. Spin filters in a josephson junction can reveal the feature of getting triplet or as an insulating ferromagnetic barrier for studying higher order harmonics also.
