Thermally isolating cabling assemblies, systems using thermally isolating cabling assemblies, and methods of fabricating thermally isolating cabling assemblies

Abstract

Cable assemblies and, systems using the assemblies can include thermal breaks between assembly sections, and methods for fabricating the assemblies can include creating thermal breaks. A cable assembly includes a first shielding cable having a first solderable material interleaved with a section of a second shielding cable having an exterior material that is a second solderable material and an inner material that is superconductive at and below a critical temperature. The cable assembly may be fabricated during the assembly of an apparatus, and, following assembly of the apparatus, a segment of the second shielding cable is etched to expose a portion of the inner material. Following fabrication of the cable assemblies, the apparatus may be installed in a cryogenic environment in which the exposed portion of superconductive inner material thermally isolates the cabling assembly proximate to a superconducting circuit from the remaining cabling assembly.
