Realization of a new digital Josephson impedance bridge combined with a graphene quantum Hall device

Stephan Bauer and his colleagues at the Physikalisch-Technische Bundesanstalt (PTB) have published a new paper on the new digital Josephson impedance bridge realized within the GIQS project.

The bridge allows the comparison of a generic impedance standard with the quantum Hall resistance in a graphene quantum Hall device. The paper is open access and you can download it immediately!
