Abstract

A quantum electro-mechanical metrology suite (QEMMS) is being built at the National Institute of Standards and Technology (NIST). As the first instrument in his class, the QEMMS combines all three, a programmable Josephson voltage system, a quantum Hall resistor, and a Kibble balance. It provides direct realizations for six units within the International System of Units (SI) – voltage, electric current, electric resistance, length, time, and mass – and thus has a great advantage over existing Kibble balances in terms of operation and calibration uncertainty. The goal is to measure masses in the range of 10g to 200g, targeting a total combined uncertainty of 2×10-8 on masses of 100g.
