We have realized submicron tunnel ferromagnetic Al/AlO/Al/NiFe/Al Josephson junctions (JJs) in Manhattan-style configuration for qubit applications. These junctio…
Nanoscale spin ordering and spin screening effects in tunnel ferromagnetic Josephson junctions
Roberta Satariano, Anatoly Fjodorovich Volkov, Halima Giovanna Ahmad +10
Magnetic Josephson junctions (MJJs) have emerged as a prominent playground to explore the interplay between superconductivity and ferromagnetism. A series of fascinating experiment…
Towards novel tunability schemes for hybrid ferromagnetic transmon qubits
Halima Giovanna Ahmad, Raffaella Ferraiuolo, Giuseppe Serpico +12
Flux tuning of qubit frequencies in superconducting quantum processors is fundamental for implementing single and multi-qubit gates in quantum algorithms. Typical architectures inv…
Evidence of the inverse proximity effect in tunnel magnetic Josephson Junctions
Roberta Satariano, Anatoly Fjodorovich Volkov, Halima Giovanna Ahmad +11
Magnetic Josephson Junctions (MJJs) are a special class of hybrid systems where antagonistic correlations coexist, thus providing a key for advances in weak superconductivity, supe…
