A video, available online, on the importance of measuring small electric currents has been created by EMPIR consortium.

Single-electron sources that generate currents by transferring an exact number of electrons per cycle offer a direct method for the realisation of the new SI ampere.

EMPIR project Quantum realisation of the SI ampere (15SIB08 e-SI-Amp) will develop capabilities to fabricate, test and validate single-electron sources, to support the redefinition and ensure consistent measurements in industry.

The project consortium has created a video, aimed at stakeholders and the general public, describing the importance and impact of developing the metrological capability for measuring small electric currents.

This video is available on the project website and also on YouTube.
In addition, a publication on the realisation of the programmable quantum current generator (PQCG), was featured on the American Physical Society’s Physics: Viewpoint.
