Validation of a quantized-current source with 0.2 ppm uncertainty

We report on high-accuracy measurements of quantized current, sourced by a tunable-barrier single-electron pump at frequencies \(f\) up to \(1\) GHz. The measurements were performed with a new picoammeter instrument, traceable to the Josephson and quantum Hall effects. Current quantization according...
