Advancing Europe’s aim to be a global leader in quantum technologies by 2030

Quantum technologies are of utmost importance for the European community from computing and communications to health, finance, transport and national security. The maturation of radio frequency (RF) quantum, semiconductor, and electronic device technologies capable of operating at extreme cryogenic temperatures is critical as these enable useful quantum systems. Progress has been hindered by the lack of traceable, accurate cryogenic RF measurements, limiting device validation, design optimisation, and scalability.

New Metrology Partnership project Cryogenic RF measurements for quantum and semiconductor technologies (25IEM08, CryoRF) brings together a global consortium of 19 organisations which spans across eight European countries to address these measurement challenges. The consortium includes seven NMIs, five research institutions and universities, and seven industrial companies.

The project will establish a European infrastructure for cryogenic RF metrology, extending International System of Units (SI) traceability and enabling robust measurements up to 40 GHz under cryogenic conditions. This initiative will accelerate innovation and position Europe as a global leader in quantum and semiconductor technologies. To support commercialisation of high-performance and reliable quantum and cryogenic semiconductor circuits for these applications, industry needs traceable measurement capabilities across several key areas:

• S-parameter measurements of connectorised and on-wafer cryogenic and quantum circuits up to 40 GHz at temperatures down to tens of milli-kelvin
• Cryogenic RF power measurements using both classical and quantum-based methods

• Cryogenic RF noise measurements of low-noise amplifiers operating in classical and quantum regimes

The project will work on these challenges and help strengthen measurement confidence across the quantum, semiconductor and electronics sectors, supporting innovation in technologies that depend on accurate cryogenic RF measurements.

This Metrology Partnership project has received funding from the European Partnership on Metrology, co-financed by the European Union Horizon Europe Research and Innovation Programme and from the Participating States.
