Abstract

The invention relates to a method for predicting performance of a nano diameter rare earth vacancy color center. The method comprises the following successive steps of constructing a model, performingtheoretical calculation, analyzing a result and obtaining a conclusion. The method for predicting the performance of the nano diameter rare earth vacancy color center realizes high calculation speedand high result accuracy. Not only can an experiment result be verified and analyzed, but also direct theoretical guidance can be supplied for laboratory preparation of the nano diameter rare earth vacancy color center. The method does not require a large number of experiment materials and instruments and has advantages of low cost, high efficiency and no pollution. The method saves manpower, material resource and financial resource. The method can facilitate researching of a single-photon source and lays a basis for researching in a quantum information field. The rare earth element has a unique light emitting advantage as an optical material. The method combines the application of the advantages in the nano diamond color center and predicts excellent property in the nano diamond color center.

Description

technical field [0001] The invention belongs to the technical field of micro-nano optoelectronic devices and photonic device engineering, and in particular relates to a method for predicting the properties of nano-diamond rare earth vacancy color centers. Background technique [0002] Single photon source is an important foundation of quantum information technology (quantum communication, quantum computing). In recent years, my country's quantum communication technology has developed rapidly. The first commercial quantum communication trunk line (Hangzhou-Shanghai) has been put into operation. However, there are relatively few studies on the preparation of single photon sources in my country. The single photon sources used by many quantum communication technology and single photon source performance research groups in my country come from abroad. Therefore, for the smooth development of quantum information technology in our country, we should vigorously strengthen the res...
