Scalable Flexible Coaxial Ribbon Cables for High-Density Quantum Wiring (Part I)
ORAL
Abstract
Superconducting electronics often require high-density microwave interconnects capable of transporting signals between temperature stages with minimal loss, cross talk, and heat conduction. We report improvements on the design and fabrication of superconducting 53 wt% Nb-47 wt% Ti (Nb47Ti) FLexible coAXial ribbon cables (FLAX). The cables are designed to operate up to 20 GHz and use G3PO coaxial push-on connectors. 3D E&M simulations were performed to optimize the connector transition, predict the cable characteristic impedance, and inform manufacturing decisions. The design improvements are being incorporated into a roll-to-roll manufacturing system by Maybell Quantum Industries in preparation for offering the cables commercially. The presentation will detail improvements to the design and provide updated performance metrics in comparison with existing commercial solutions.
