Fabrication of Al/AlOx/Al junctions with high uniformity and stability on sapphire substrates
Abstract Tantalum and aluminum on sapphire are widely used platforms for qubits of long coherent time. As quantum chips scale up, the number of Josephson junctions on sapphire increases. Thus, both the uniformity and stability of the junctions are crucial to quantum devices, such as scalable superco...
