Applications

Quantum Computing
Quantum computing architecture creates stringent requirements on i/o for qubit control. The cryogenic cable Cri/oFlex® 2 and Cri/oFlex® 3 series are designed specifically for crowded setups and provide excellent microwave performance.

Quantum Internet
Quantum internet research is developing rapidly and requires a growing number of SNSPD i/o channels. Our multi-channel flexible cryogenic cable is dedicated for quantum communication applications.

STM & SPM
Scanning probes and moving stage experiments at low temperatures have been waiting for ultra-thin cables with excellent RF and cryogenic properties. Check out our flexible cryogenic cable Cri/oFlex® 1 series with an unprecedented footprint.

Case study highlights
Superconducting Qubits Case Study
- Delft, The Netherlands
- ImpaQt Consortium
- Quantum Computing
We successfully measured and characterized working transmon qubits with lifetimes up to 15 µs. Showing that Cri/oFlex® 2X is well suited for transmon qubits and can drastically reduce installation time due to their compact size, flexibility, and integrated filters.
