We have an upcoming joint webinar with Delft Circuits – Overcoming Cryogenic Cabling Challenges within Dilution Refrigerators for Effectively Scaling Quantum Computing – scheduled for June 11, 9am PST. You can register here.

A major challenge in scaling quantum computing systems is the severe limitation imposed by conventional cryogenic cabling within dilution refrigerators (DRs). As qubit counts increase, the volume of coaxial cables required quickly overwhelms the available space, creates an excessive heat load that exceeds the DR’s cooling capacity, and presents significant installation difficulties. These physical and thermal bottlenecks are a primary barrier to achieving higher qubit numbers within standard laboratory footprints and budgets.

This presentation will demonstrate how the innovative Cri/oFlex® technology from Delft Circuits (DC) can address the challenges faced in a FormFactor LF600 lab-scale dilution refrigerator, including:

  • Replacing coaxial cables with flexible, high-density stripline I/O systems featuring integrated filtering and specialized connectors for a significantly smaller wiring volume and drastically reduced heat load per channel compared to conventional methods.
  • Showing how this technology increases channel counts from 50 to 500 and enables up to 100 qubits within a lab-scale DR, without compromising performance.
  • Comparing performance and density to conventional cabling within the context of DR cooling power
  • Outlining the design, manufacturing, assembly, and installation process.

The presentation will conclude by highlighting the capability of DC cables to significantly increase channel density and qubit count within existing lab infrastructure. This approach offers options for even larger systems using bigger dilution refrigerators (DRs). It provides a scalable, robust, and user-friendly I/O system, offering a space- and budget-efficient path toward future, higher-qubit quantum processors.

Moderator: Jack DeGrave, Director of Business Development, FormFactor Inc.

Jack DeGrave has been an integral part of the FormFactor-HPD Business Development team since early 2021, where he has been instrumental in engaging with Quantum Development Community members to identify and address the needs for cryogenic test and measurement, high-density I/O device interfacing, and cryostats for quantum processor deployment. Jack’s expertise in cryogenic test and measurement dates back to his PhD studies at the University of Wisconsin-Madison, where he researched low-temperature transport properties of helimagnets and skyrmions starting in early 2010. Following his graduation, Jack held various business development positions at leading cryogenics companies, accumulating over a decade of experience in cryogenic system design and test & measurement.
