e-SI-amp: Quantum realisation of the SI Ampere

2016–2019          Realisation and dissemination of the future SI ampereEmma.jpg

New methods for the realisation of the future SI ampere are needed, as the redefinition of the SI units would base the definition of the ampere on an
exact value of the elementary charge e.

Project develops accurate current sources based on the transfer of single electrons and improves the traceable dissemination of quantum-metrological
current standards to end users.

MIKES characterises single-electron pumps and makes direct comparisons
of pumps by current null measurements.
