Microwave metrology for superconducting quantum circuits

Project: EU project

Project Details


Cryogenic microwave metrology to support quantum technology

All emerging solid-state approaches for quantum computing and many other quantum technologies rely on microwave signals. Yet, no established technology exists today that can perform accurate waveform generation and signal metrology under their operating temperatures below 4 K.

Project develops novel microwave metrology tools to synthesise and validate microwave signals in-situ at cryogenic temperatures using a combination of superconducting, semiconducting, and
optical techniques.

VTT MIKES develops an optically integrated Josephson arbitrary waveform synthesizer with unprecedented bandwidth (> 100 GHz) utilising a recent VTT invention, optical pulse pattern generator.

Call 2020: Fundamental Metrology

This project has received funding from the EMPIR programme co-financed by the Participating States and from the European Union’s Horizon 2020 research and innovation programme.
