The sector develops metrological tools and infrastructures for quantum computing and sensing. It establishes traceable measurement methods for qubits and cryogenic microwave systems, investigates decoherence and noise, and defines calibration, benchmarking and validation procedures for scalable quantum technologies.

The sector develops advanced metrological tools and infrastructures to support quantum computing, sensing and superconducting quantum technologies. Activities focus on traceable measurement methods and harmonised protocols for the characterisation of qubits, parametric amplifiers and cryogenic microwave systems operating at millikelvin temperatures.

In quantum computing, the sector investigates decoherence mechanisms, noise sources and device reproducibility, developing benchmarking and uncertainty evaluation procedures for reliable qubit metrics. In quantum microwave metrology, it establishes in-situ calibration techniques, noise thermometry and traceable temperature control for complex cryogenic readout chains.

Within quantum sensing, the sector validates non-classical microwave sources and quantum-enhanced detection schemes, contributing to standardisation and best-practice guidelines for scalable quantum technologies.
