The project “In-situ calibration technology based on quantum effect†was held
[ Instrument Network Instrument Development ] On October 23, the National Key R&D Program “Making Basic Technology and Key Components†key project “Instrument Calibration Technology Based on Quantum Effect†was launched at the China Institute of Metrology (hereinafter referred to as “ China Metrology Institute was held. Experts from the Institute of Microelectronics of the Chinese Academy of Sciences, the Institute of Physics of the Chinese Academy of Sciences, the Institute of Electrical Engineering of the Chinese Academy of Sciences, the Beijing Institute of Metrology and Measurement, the Beijing Institute of Metrology and Measurement, the Institute of Metrology and Measurement Technology of Beijing, and the national market. More than 20 people including the relevant leaders of the Science and Technology and Finance Department of the General Administration of Supervision, the heads of relevant functional departments and the technical backbone of the project participants participated in the kick-off meeting. Song Shuying, vice president of China Metrology Institute, attended the meeting and delivered a speech.
Start to attend the meeting
The project leader Zhao Jianting, associate researcher, introduced the overall situation of the project and the schedule of the project tasks. The project leaders reported the research content and technical solutions of the project.
The consulting expert group listened carefully to the report, focusing on the preparation of the Josephson chip, the construction of the quantum voltage source, and the application of the in-situ calibration. After discussion, the participating experts agreed that the project was difficult and time-intensive. The research content proposed by the project team was substantial, the technical route was feasible, and the task schedule of the project and the project was detailed and reasonable.
Start meeting
The project is jointly conducted by China Metrology Institute and the Institute of Microelectronics of the Chinese Academy of Sciences, Beijing Oriental Metrology and Testing Institute, and the Institute of Mechanical Industry Instrumentation and Comprehensive Technology and Economics. Through the breakthrough of large-scale superconducting integrated quantum voltage chip preparation, magnetic flux quantum regulation And other technologies to develop AC quantum voltage standard devices. Based on the relevant quantity value transfer and instrument in-situ calibration method to realize the in-situ calibration of electric measuring instruments, it provides support for the technical research and development of domestic related testing and measuring institutions and industry-leading enterprises, and enhances the research and development level of domestic enterprises in the field of advanced electromagnetic instruments and meters. International competitiveness. (Text: Zhou Yitu: Song Hailong, Gao Ying)
