Advanced quantum technology for metrology of electrical currents

Project: EU project

Project Details


Robust, wide-range primary quantum standard of the electrical current 

In electrical quantum metrology, the Josephson voltage and the quantum Hall resistance standards are robust primary quantum standards that directly exploit the definition of the SI by fundamental constants. In contrast, a direct, wide range, gapless, and robust primary quantum standard for electrical currents is still elusive for the wide range of small current levels.

Project develops a primary quantum standard of the electrical current that, based on novel quantum technologies, is direct, wide range, gapless, robust.

VTT MIKES performs cryogenic characterisation of Si single-electron devices fabricated by SemiQon.

Call 2023: Fundamental Metrology 

The project (23FUN05 AQuanTEC) has received funding from the European Partnership on Metrology, co-financed from the European Union’s Horizon Europe Research and Innovation Programme and by the Participating States.
