Systems Visions LLC (dba SYVI) and its partner Auburn University (AU) propose "Silver-Aluminum-Niobium Tri-conductor Architecture (SANTA) based connectorized high density temperature agnostic microwave cables for cryogenic applicationsâ, an effort to develop a high-density cabling solution for cryogenic high performance and quantum computing applications. The cables will leverage a unique tri-conductor metal stack for signal conduction that will allow the cable to transition seamlessly between different temperature zones. Furthermore, a critical need exists in the area of high-density, high-performance, multi-signal, microwave connectors for interfacing the high signal density cables, therefore a significant part of this effort involves enhancing current versions to realize high-density connectorized cables. The overarching goal of this proposed work is to make a substantial impact on the interconnect challenges for scaled-up systems and lay the foundation for creating the interconnect technology required to realize densely-integrated cryogenic computing architectures and reach superconducting quantum computers with 1M physical qubits
