Development of Tuxedo: a super-conducting flex-to-pcb interface connection for quantum technologies

Delft Circuits designs, manufactures, and sells disruptive innovative hardware for the quantum and cryogenic industry. IDelft Circuits (DC) designs, manufactures, and sells disruptive innovative hardware for the quantum and cryogenic industry. Its product Cri/oFlex offers a scalable cryogenic input and output (i/o) solutions used by customers around the world. Cri/oFlex controls and reads quantum devices operating at cryogenic temperatures via a flexible substrate (flex), offering superconducting, high-density, high-performance cabling with low thermal load, minimal noise and integrated filters. The quantum industry is booming and aims to capitalize on the huge potential of quantum for all kinds of computing problems, such as AI, machine learning and complex optimization problems. The industry needs to scale from 100+ qubits now to 10k qubits in a few years, increasing the number of i/o channels. As the number of i/o channels continues to grow, the possible points of failure grow with it and costs start to explode as (coaxial) components get smaller. To scale the number of qubits per system, reliability and ease of use need to increase, while costs need to decrease. High-density, low-cost and high-performance interfacing is critical in the 10k-qubit system value chain, but it is currently missing. We can now leverage Cri/oFlex, using all current and proven aspects of Cri/oFlex to solve the interfacing bottleneck with Tuxedo. Tuxedo is an interface between Cri/oFlex and super-conducting pcbs. With Tuxedo, we can achieve the interface for a very high density of signal lines against relatively low costs in a scalable architecture. With Cri/oFlex, DC has extensive experience in developing an innovative product from research to commercially ready and beyond, and DC sees all the potential of Tuxedo to be willing to invest in developing it to become ready for marketing at scale. With support of the EIC, DC can accelerate their development roadmap for Tuxedo effectively.
