| Abstract: | Spontaneous parametric down-conversion(SPDC)is a primary method for preparing quantum light sources.In this paper,the central technical schemes of different types of SPDC(type-0,type-Ⅰ,type-Ⅱ)were introduced,and the research progress and applications of quantum light sources to prepare multi-photon quantum entangled states and high-dimensional quantum entangled states were discusseed.At the same time,the preparation and application of narrow linewidth entangled states from cavity-enhanced SPDC were also introduced.Finally,the existing problems and future development direction of various schemes were analyzed and prospected. |
