Submicrometer tunnel ferromagnetic Josephson junctions with transmon energy scale

R. Satariano, R. Ferraiuolo, F. Calloni +5

We have realized submicron tunnel ferromagnetic Al/AlO${}_x$/Al/Ni${}_{80}$Fe${}_{20}$/Al Josephson junctions (JJs) in Manhattan-style configuration for qubit applications. These junctio…
