Evolution Towards Quantum Metrology and the Action Agenda for Developing IT-Enabled Metrology

Abstract

Quantum metrology and informatization of metrology are two major directions for metrology innovation. A new generation of information technologies, represented by the Internet, big data and artificial intelligence, are booming and has brought a far-reaching impact on scientific research around the world. In 2018, the General Conference on Weights and Measures (CGPM) at its 26th meeting adopted a Resolution on the revision of the International System of Units (SI) to redefine all SI base units in terms of physical constants. This revision terminated the history of using artefacts as measurement standards, and ushered in a new era of “modern metrology” where measurements are largely based on quantum technologies. China has played a vigorous part in the global research cooperation enabling the SI revision. Furthermore, China has proposed to establish a quantum-based national advanced measurement system where quantum measurement standards and a “flattened” traceability chain will be the core features. This action will help incorporate quantum metrology into informatization programmes of China, accelerating the integration between quantum technology and information technology.
