"From pioneering flexibility to proven quality, we now add the standardization that quantum industry growth depends on — ensuring your systems are ready to scale."

By partnering with Bluefors, Delft Circuits ensures that Cri/oFlex® integrates seamlessly into complete quantum systems. For customers, this means faster setup, fewer risks, and solutions that scale in harmony with the rest of the industry. Together with Bluefors, we deliver turnkey reliability — so you can focus on quantum progress, not cabling challenges.

Bluefors interim CEO and founder, Rob Blaauwgeers, explains the benefits of the new partnership for customers:

“Delft Circuits is at the forefront of flexible cabling technology. Our extensive testing has confirmed that their Cri/oFlex® solution delivers microwave performance on par with conventional coaxial solutions, while offering superior thermal performance. Together, we can now provide customers with a complete, future-proof solution to their quantum research and development.”

Product Highlights

Pre-assembled and tested side-loading systems for easy and reliable installation

Monolithic, flexible wiring design improves reliability and decreases system downtime

High-density, scalable, and modular i/o due to thin-film, multi-channel design

Designed for superconducting qubits due to optimized integrated signal conditioning

Choose your configuration. Flux bias only, Microwave Drive only, half-half, quarter-three quarters

SMP connectors on both Room Temperatue and MilliKelvin node allow for flexibility

With Cri/oFlex®, reliability is built in.

By integrating components such as attenuators and filters directly into the flex, we eliminate extra parts and reduce points of failure. Combined with fast thermalization at every temperature stage, our technology ensures stable performance across thousands of channels — delivering reliability unmatched by any other I/O solution.
