Claim 0:
1. A superconducting quantum computing circuit package comprising:
a substrate on which a superconducting quantum computing circuit is formed, wherein the superconducting quantum computing circuit comprises a plurality of circuit elements and the substrate comprises one or more holes arranged between the plurality of circuit elements, wherein the one or more holes extend through a thickness of the substrate; and
a holder comprising a surface on which the substrate is received and a cover arranged on an opposite side of the substrate from the holder, wherein the holder and the cover are formed from a metal and/or a superconductor and the holder comprises one or more projections arranged on and projecting from the surface;
wherein the one or more projections protrude through the one or more holes in the substrate and contact the cover so to suppress electromagnetic modes in the frequency range of operation of the quantum computing circuit; and
wherein the holder comprises one or more apertures formed through the surface of the holder, wherein the superconducting quantum computing circuit package comprises one or more wires arranged to pass through the one or more apertures respectively to connect to the quantum computing circuit.
