The Expanding Role of National Metrology Institutes in the Quantum Era

Now that all base units are defined in terms of fundamental constants and can thus — at least in principle — be realized anytime and anywhere, rather than through a measurement chain leading back to unique physical artefacts, who holds the traceability chains? Quantum technologies enable the realization of high-precision standards both within laboratories and in the form of miniaturized, intrinsically accurate and quantum-referenced sensors. Combined with the new pathways for traceability opened up by the SI redefinition, they pose both an exciting challenge and a tremendous opportunity for NMIs.
