Delft Circuits is a hardware company that produces cryogenic microwave cables for quantum computation, astrophysics, and cryogenic applications.

Cri/oFlex® is a high-frequency cryogenic wiring solution based on conducting circuits on flexible substrates. Designed specifically for cryogenic setups, it provides excellent microwave performance, low thermal load, flexibility, ease of installation and reliability. Cri/oFlex® wiring is an ideal solution for scaling superconducting and other solid-state qubit count, and photonics detectors.

Founded in 2016 as a spin-off from the University of Technology, Delft Circuits is one of the oldest quantum companies in Delft.
