Professor Hyojung Kim of Kumoh National Institute of Technology Leads Korea’s International Standardization in Quantum Technology

Korea's First International Standard Proposal Approved for "Quantum Light Source Measurement"
Korea Takes the Lead in Quantum Standards
Enhancing the Reliability of Single-Photon Source Measurement

The new international standard project on quantum technology, led by Professor Hyojung Kim from the Department of Optical Systems Engineering at Kumoh National Institute of Technology (President: Kwak Hosang), has been officially approved by the International Electrotechnical Commission/International Organization for Standardization Joint Technical Committee 3 (IEC/ISO JTC3, Quantum Technologies).

This means that the new technology proposal has been formally adopted and will proceed through stages such as committee drafts and questionnaires, ultimately to be published as an International Standard (IS) or Technical Specification (TS).

This achievement marks the first time that an international standard (Technical Specification) in the field of "quantum light source measurement" proposed and approved by Korea has been recognized, and it is considered a significant accomplishment, as Korean researchers have taken the lead in international standardization discussions.

The approved standard, "PNW TS JTC3-119," addresses a Hanbury-Brown-Twiss (HBT) interferometer-based measurement method for quantitatively evaluating the characteristics of single-photon sources.

In particular, it defines and sets evaluation criteria for the key parameter g2(0), which indicates the purity of a single-photon source. This is expected to contribute to enhancing the reliability and international compatibility of the quantum materials and quantum communications industries in the future.

As the Korean lead proposer, Professor Hyojung Kim spearheaded the project, securing participation from experts in more than seven countries-including Canada, Denmark, Germany, Italy, China, and Brazil-and gained approval with the support of 87.5% of member countries.

Despite diverse perspectives from various countries, the scientific validity and importance of international collaboration were acknowledged, resulting in Korea's first approval of an international standard for "quantum light source measurement" under Korean leadership.

Professor Hyojung Kim stated, "This approval is a meaningful achievement that demonstrates the reliability of quantum light measurement and Korea's leadership in international standardization to the world. In the next development stages, we will further specify detailed measurement procedures and data analysis criteria, and enhance the completeness of the standard by strengthening collaboration with international experts."
