Fig. 6: State-of-the-art of the accuracy of quantum current sources and current generation.
From: A primary quantum current standard based on the Josephson and the quantum Hall effects
Comparison between the relative uncertainty achieved in the generation of currents traceable to the ampere using the PQCG (this work and ref. 27) and others quantum current sources: metallic (8,54), GaAs (9,11,14) and Si (12,13) SECS, series connection of QHRS array and PJVS for generating (24) current. CMCs (black line)55. Inset: \(\overline{{\Delta }I/I}\) measurements performed in this work (orange diamond) as a function of current value I. The value at 45.94 μA corresponds to the weighted mean of \(\overline{{\Delta }I/I}\) values obtained using N1 = 160 and N1 = 465.
