Scalable Flexible Coaxial Ribbon Cables for High-Density Quantum Wiring (Part II)
ORAL
Abstract
As quantum processors increase in complexity, fitting sufficient high-quality input/output (I/O) and RF data cables and connectors into the limited footprint of a dilution refrigerator is becoming increasingly complex. Traditional semi-rigid RF cables have a large footprint, thermal load, and stiffness. A novel Ribbon Cable has been developed on-scale which offers high density, low attenuation, low crosstalk, low heat load, and low production costs. In this presentation we share progress on the cable production system using a custom laser welding technique to produce a low-cost, high-performance quantum I/O solution. Cable properties, including heat load, pitch density, and contact resistance between the cables and connectors have been calculated and measured at 300K, 4K, and 100mK for superconducting and non-superconducting FLEX lines are reported and show the cable's suitability as a high-density cable solution.
