Metrology for Quantum Hardware Standardization—Charting a Pathway: A Strategic Review

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1282-1296, September 2026.
Advances in quantum mechanics have long underpinned metrology by enabling practical realizations of units through quantum effects. With the 2019 SI revision, traceability is anchored in defined fundamental constants, reinforcing the quantum‐mechanical basis of modern standards. In parallel, quantum technologies are transitioning from laboratory science
