Input/output systems and devices for use with superconducting devices

An input/output system for use with a superconducting device sample, the input/output system comprising:

• a first tier including a first set of electrical filter structures, wherein each of the electrical filter structures in the first set of electrical filter structures comprises a respective lumped element filter that is at least partially contained within a respective enclosure, and wherein each of the electrical filter structures in the first set of electrical filter structures has an input end and an output end;
• a first set of electrical signal paths, each of the electrical signal paths in the first set of electrical signal paths including a filter input portion, a filter portion, and a filter output portion, wherein the filter input portion of each respective one of the electrical signal paths in the first set of electrical signal paths communicably couples to the input end of a respective one of the electrical filter structures from the first set of electrical filter structures, the filter portion of each respective one of the electrical signal paths in the first set of electrical signal paths includes at least a portion of the lumped element filter of a respective one of the electrical filter structures from the first set of electrical filter structures, and the filter output portion of each respective one of the electrical signal paths in the first set of electrical signal paths communicably couples to the output end of a respective one of the electrical filter structures from the first set of electrical filter structures, wherein at least a portion of each one of the electrical signal paths in the first set of electrical signal paths is superconducting and each one of the electrical signal paths in the first set of electrical signal paths provides electrical communication with at least a portion of the superconducting device sample;
• a first composite plate structure having a first top plate and a first bottom plate, wherein the first top plate and the first bottom plate mate to form a first inner volume therebetween on a first side of the first top plate, and wherein each of the electrical filter structures in the first set of electrical filter structures is carried by a second side of the first top plate that is opposite the first side of the first top plate such that the filter output portion of at least one of the electrical signal paths from the first set of electrical signal paths extends from the second side of the first top plate, through the first top plate, and into the first inner volume;
• a pedestal mounted to the first side of the first top plate inside the first inner volume;
• and
• a device sample holder assembly selectively mountable to and dismountable from the pedestal inside the first inner volume, wherein the device sample holder assembly includes at least one printed circuit board, at least a portion of the device sample holder assembly superconductingly electrically couples to at least one of the electrical signal paths from the first set of electrical signal paths, and at least a portion of the device sample holder assembly superconductingly electrically couples to the superconducting device sample.
