- 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-1, type-) 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.
