摘要： A device includes: a substrate; a first superconductor layer on the substrate, the first superconductor layer having a first kinetic inductance; and a second superconductor layer on the first superconductor layer, the second superconductor layer having a second kinetic inductance that is lower than the first kinetic inductance, in which the second superconductor layer covers the first superconductor layer such that the second superconductor layer and the first superconductor layer have a same footprint, with the exception of at least a first region where the second superconductor layer is omitted so that the first superconductor layer and the second superconductor layer form a circuit element having a predetermined circuit parameter.

摘要： The disclosed device (100) includes a first chip (102) comprising a quantum circuit element, particularly a superconducting quantum bit, and a second chip (104) bonded to the first chip. The second chip includes a substrate (108) having first and second opposing surfaces, the first surface (101) facing the first chip including a single layer (105) of superconductor material, and the second surface (103) including a second layer (107), preferably comprising superconductor material layers (113) and including a second circuit element. Preferably, a through connector (109) extends from the first surface to the second surface and electrically connects a portion of the single layer of superconducting material to a second circuit element.
