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

Cri/oFlex® 1

Ultimate cryogenic flexibility​

Ultra-flexible microwave i/o for scanning probe microscopes and other vibration sensitive instruments. The thinnest and the most flexible cryogenic RF cable allows you to transmit your signal while offering extreme vibrational decoupling.

Cri/oFlex® 2

The new cryogenic microwave standard

Single channel microwave i/o for densely-packed sample spaces in the refrigerators. Simple installation, small form-factor and reduced thermal loads, allow an increased number of microwave lines in cryostats. This flexible cryogenic cable is a new standard.

Cri/oFlex® 3

Massively scalable cryogenic i/o

Massively scalable multi-channel flexible RF cable for refrigerators, optimized for quantum computing applications with built-in on-flex filtering for signal conditioning.

 

Case study highlights

Scaling Up SNSPD Readout

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…
