摘要
A fluxonium qubit includes a superinductor. The superinductor includes a substrate, and a first vertical stack extending in a vertical direction from a surface of the substrate. The first vertical stack includes a first Josephson junction and a second Josephson junction connected in series along the vertical direction. The superinductor includes a second vertical stack extending in a vertical direction from a surface of the substrate. The second vertical stack includes a third Josephson junction. The superinductor includes a superconducting connector connecting the first and second vertical stacks in series such that the first, second, and third Josephson junctions are connected in series. The fluxonium qubit further includes a shunted Josephson junction connected to the superinductor with superconducting wires such that the first, second, and third Josephson junctions of the superinductor that are in series are connected in parallel with the shunted Josephson junction.
