Introduction

1. Standardization background and technological evolution

GB/T 43737-2024 "Quantum Measurement Terminology" is the latest standard jointly issued by the State Administration for Market Regulation and the National Standardization Administration, which aims to unify the terminology definitions in the field of quantum measurement and standardize the compilation of relevant technical documents and textbooks. This standard is based on the International Standardization Work Guidelines (GB/T 1.1) and fully considers the rapid development needs of quantum computing and measurement technology.

2. Core term analysis

Terminology	Definition	Application scenario
Quantum measurement	Obtain the state of a quantum system and measure it using its minimum, discrete characteristics.	Used in the development of quantum sensors and quantum metrology equipment.
Heisenberg uncertainty principle	The physical relationship that two non-commutative observables cannot be determined simultaneously.	Used in quantum sensing to define precision limits.
Quantum interference	The phenomenon of constructive or destructive amplitudes of quantum states.	Applied to atom interferometers and optical frequency comb technology.

3. Technical framework and typical applications

3.1 Comparison of standardization frameworks

The comparison of the terminology between GB/T 43737 and international standards shows that my country's research in the field of quantum sensing and quantum metrology has reached the international leading level.

3.2 Analysis of typical applications

Atomic clock: A high-precision time standard based on microwave or optical frequency transitions.
Superconducting quantum interference device: A key device for extremely weak magnetic field measurement.
Diamond color center magnetometer: A high-sensitivity magnetic field detection technology based on nitrogen vacancy color centers.

4. Implementation Suggestions

To ensure the effective implementation of the standard, it is recommended that:

Strengthen the popularization and training of quantum measurement technology.
Promote the application demonstration of quantum sensors in the field of precision measurement.
Establish a standardization laboratory to support the research and development and testing of related equipment.
