What it does. Where it fits.
Passive and electromechanical RF signal-chain components qualified or engineered for cryogenic use.
Who should look closer
Superconducting and cryogenic quantum teams selecting microwave routing and switching components.
QubitWire’s editorial assessment of practical fit.RF components by part number
Product documentation lists switch, cable and attenuator configurations; procurement and engineering support are available through Radiall.
Check the current access route ↗What has been demonstrated
NPL confirms cryogenic device characterization; QphoX confirms compatibility testing of specific Radiall switches with its controller.
What remains unresolved
The NPL announcement does not publish the measured S-parameter dataset. Interoperability is verified for named switch models and does not establish every configuration or long-term switching lifetime.
The next question to watch
Publish traceable cryogenic datasets and repeated switch-cycle results for installed quantum systems.
A research question, not a promised milestone.QubitWire coverage
