Cryogenic wiring at your fingertips using Cri/oFlex®
Cri/oFlex® product platform
For the input/output (i/o) chains of cryogenic quantum computing, communication and sensing play an essential role in its performance. Especially in larger systems, cabling or component failure, passive heatload and limited space can be a challenge.
Cri/oFlex® is designed specifically for cryogenic (quantum) systems and provides a scalable platform with fully integrated filtering, a small footprint and low heatload.
At Delft Circuits, it is our goal to be a one-stop shop for cryogenic i/o assemblies. To accomplish this goal we have developed three modules. Firstly the interconnect module consisting of electrical- and microwave interfaces, as well as vacuum feedthroughs and thermal anchoring. Secondly, two material platforms (flex laminates) for signal transmission and lastly on-flex integrated components for signal conditioning.
With these three modules we can tackle every cryogenic i/o challenge!
- I/O channel configuration
The most important choice for your I/O is the type of signal it is configured to transmit.
- Cryogenic platform integration
Cri/oFlex® can be integrated into your cryostat in multiple ways. Click to find out more.

Especially for large channel capacity solutions – a few hundred-, dedicated engineering is required to come with an optimal solution
I/O channel configuration
Cri/oFlex® offers many possibilities to taylor the I/O-chain specification to your application needs. The most typically produced configurations are packaged in a standard configuration:
Mix & Match lines
For special applications where specific I/O chain configurations are required, Cri/oFlex® offers the possibility to Mix & Match specific I/O chains from standard available sections.
Available I/O Sections
- Vacuum Feedthrough
- RT - 4 K
- 4 K to 10 mK

System Engineering
In I/O design for cryogenic applications a carefull balance has to be found between thermodynamic and electrodynamic parameters. The versatile Cri/oFlex® technology is able to be adjusted to different boundary conditions, with our internal experts, we are able to configure, design and build your optimal I/O solution. Of course on-site installations is part of our job.
Software & Calibration
With Cri/oSuite we have the tools to model the microwave and thermal response of each I/O chain. It is integrated into our experimental setup allowing all components to be calibrated to their temperature specific profile.
