GB/T 43784-2024 in English

1. Background and significance of standard formulation

With the rapid development of quantum computing and quantum communication technology, the single photon source, as one of the core components of quantum information science, has an increasingly urgent need for standardization of its performance characterization and measurement methods. The formulation of this standard aims to unify the performance evaluation system of single photon sources and provide clear technical specifications and test methods for scientific research institutions and enterprises.

2. Classification and key parameters of single photon sources

3. Comparative analysis of standard framework

Compared with other international standards, this standard has the following advantages in performance characterization and measurement methods:

• Comprehensiveness: Covers three types of single-photon sources: deterministic, probabilistic and quasi-single-photon sources.
• Operability: Provides specific measurement steps and formulas for practical application.
• Innovation: Introduces cutting-edge indicators such as photon isometry and coherence length.

4. Implementation Suggestions

It is recommended that enterprises pay attention to the following points during the implementation process:

• Establish a professional testing team.
• Equip with advanced photon detection equipment.
• Record and analyze data strictly in accordance with standard requirements.
