On 25th November, QPhotoniX 2023 was held in Jinhua, Zhejiang Province, China, and CAS Cold Atom was invited to attend the conference. With the theme of "Quantum Light Illuminates the Future", the conference focuses on quantum computing, quantum communication, quantum precision measurement and related industries to carry out academic seminars and application docking, etc. It is also the largest and highest specification academic feast in the field of quantum photonics in China.
During the same period of the conference, the "Quantum Photonics Excellent Achievements Exhibition" was held, and the core product of Zhongke Kukyuan, the High-precision compact absolute quantum gravimeter, was selected and invited to share on-site.
This gravimeter participated in the 11th International Comparison of Global Absolute Gravity Instruments (ICAG 2023) held in Boulder, U.S.A., in September 2023, and it not only has high compactness and stability, but also achieves ultra-high gravity measurement sensitivity. This is of great significance for the localisation and commercialisation of high-precision absolute gravimeters, which have broad application prospects in the fields of geodesy, geophysics and metrology.
