# Quantum Metrology: How China Is Building the Measurement Standards of the Future and Challenging the US

## 🎯 Key Points

- China has approved a five-year quantum metrology development plan under SAMR's aegis, aimed at technological independence
- Calibration precision of one nanometer is critical for microchip production and determines the cost of errors
- The US has included quantum metrology in the CHIPS for America program, while China has tightened exports of rare-earth metals

China is rolling out an ambitious state strategy aimed at dominating quantum metrology — the science of ultra-precise measurements that effectively sets the benchmarks for an entire generation of future technologies. Quantum metrology harnesses the laws of quantum physics to achieve a level of precision unattainable by traditional measurement methods, and it serves as an indispensable foundation for manufacturing modern smartphones, satellites, and medical equipment. According to data outlined in an RBC review, China's State Administration for Market Regulation (SAMR) has approved a special five-year development plan whose main goal is to turn the country into an international benchmark for quantum measurement standards and to ensure full technological independence from the West. Beijing seeks to cover the entire development cycle — from fundamental laboratory research to mass industrial production.

### Why a Single Nanometer Decides Everything

The practical significance of this race becomes clear when you look at production supply chains. Without the requisite level of precision, manufacturing microchips is simply impossible: a calibration deviation of just one nanometer can ruin the results of years of research and lead to losses of millions of dollars. This is why control over measurement benchmarks is becoming a strategic asset no less important than control over chip production itself. Whoever sets the standard of precision effectively dictates the terms for the entire high-tech market.

### Optical Frequency Combs as a Showcase of Capabilities

A striking example of China's achievements in this field is the development of miniature optical frequency combs — devices that allow the frequency of light to be measured with unprecedented precision. Such tools are critical for telemetry, navigation, and quantum computing, and their miniaturization paves the way for integration into portable and satellite equipment. US export restrictions on advanced semiconductors, analysts assess, have only intensified Beijing's drive toward autonomy, while in response China has tightened controls on the export of rare-earth metals, without which the production of high-tech electronics is impossible.

### Washington's Response and Mirror Logic

The United States, for its part, recognizes the risks and has already included quantum metrology in the CHIPS for America national microelectronics development program, acknowledging it as a critical link in technological sovereignty. Thus, both sides have built a mirror logic: export restrictions on one side and countermeasures on resource control on the other. The rivalry has ceased to be point-specific and has turned into a systemic struggle over the right to set the measurement standards on which the competitiveness of entire industries will depend.

### The Stakes: From 6G to EV Batteries

The outcome of the technological race between the US and China will determine the standards of numerous industries — from the defense sector and 6G communications to satellite monitoring and the production of batteries for electric vehicles. In essence, the question is whose precision benchmarks will become the de facto global norms over the coming decades. For Kyiv and Europe, this means the need to track how a shift in measurement standards will affect the availability of components and the terms of supply for high-tech products in the region.
