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.
Products

Case study highlights
Scaling Up SNSPD Readout
- University of Münster, Germany
- Group of Prof. Schuck, Physikalisches Institut
- Quantum Internet
The primary goal was reading out a 16 SNSPD setup in a compact fridge using multi-channel i/o. This is the first stepping stone to scaling up to and beyond a 64 SNSPD setup. The system required going in a straight shot from room temperature, through the vacuum barrier, down to 3K at the chip holder where the dectector is located…
