Waveform metrology based on spectrally pure Josephson voltages

Project: EU project

Project Details


Enabling wider distribution of quantum standards

Emerging measurement applications in high-end equipment are placing new demands on
the traceability for dynamic quantities, which cannot be satisfied by existing approaches.

Project develops AC-voltage quantum devices operating at the highest level of accuracy and
that are simple enough for wider exploitation.

VTT MIKES develops a cost effective programmable pattern generator to drive Josephson junction arrays in a quantum voltage digitiser.
