A damage-free and controllable method for preparing nitrogen-vacancy centers in diamond

Abstract

The invention discloses a non-damaging and controllable method for preparing nitrogen vacancy centers in diamond. By selecting a non-metallic catalyst and a nitrogen source, the ferromagnetic defects inside the synthetic diamond are reduced, and the content of nitrogen impurities inside the synthetic diamond is controlled. By controlling the growth crystal direction The matching with the temperature precisely controls the formation type of nitrogen vacancies inside the diamond. The high temperature and high pressure annealing technology is used to quickly and effectively adjust the type of nitrogen vacancies and the number of charges inside the diamond, and a controllable NV 0 , NV ‑ , N 2 V and other nitrogen vacancy centers, thus effectively solving the problem that the lack of nitrogen vacancy controllable preparation technology seriously limits its further industrial application.

Description

Technical field

[0001] The present invention belongs to the technical field of quantum technologies and precision test materials, and therefore referring to a method of non-injurious injury to control the nitrogen space center in a diamond. Background technique

[0002] Quantum technology is an emerging cross discipline that combines quantum theory and informationism. It uses "quantum superposition" and "quantum entangled" effect to store information in "quantum bits", reach super fast parallel computing power, in supercarcies, information processing, Artificial intelligence, information security and other applications have traditional computers unparalleled advantages. In recent years, as quantum techniques come from theory to experiment, successfully develop quickly from laboratory, so that they have broad application prospects in national economic, science and technology and military, and quickly become the international quantum physics and information science.
