Abstract
This paper describes the latest improvements of the programmable quantum current generator. Here we focus on the fabrication of the new cryogenic current comparator, which will allow implementing the triple connection between the quantum Hall resistance standard and the programmable Josephson voltage standard, necessary step to reduce the correction on the generated current from few parts in 107 to few parts in 1010. Other on-going developments towards a laboratory dedicated to a new ampere traceability are also introduced.
