A microwave drive line is optimised for low loise microwave transmission up to 8 GHz. In this way one can apply microwave drive signals to your qubit or cryogenic circuit, without opening noise channels.
With 50 dB attenuation distributed over different temperature stages one obtains the optimal balance between active heat load, and opening loss channels through loss channels.
With a low-pass filter at 8 GHz and a an IR-filter on flex your circuits are maximally protected for high-frequency interference.
System Integration
There is a wide variety of cooling solutions for quantum computing and low temperature experiments, ranging from lab size dilution refrigerators to small 4K table-top systems. As an i/o provider, it is our task to connect quantum devices and cold experiments to the control electronics regardless of the cooling implementation. To that end we have developed standardized solutions that fit (or can be made to fit) all fridges.
Whether you are purchasing a new system or want to refurbish your current system, Cri/oFlex® provides a solution.
Wiring Ports
Have a spare port in your fridge and want to add extra lines or replace an existing wiring port with a higher density cabling solution?
We supply vacuum feedthroughs, Thermal clamps, Brackets and Cri/oFlex® laminates for all standard ports you will find in dilution refridgerators.
