Abstract

Abstract: We review recent progresses on entanglement entropy and Page curve of black holes, and discuss the relationship between entanglement entropy and geometry. As is well-known, there are four fundamental interactions in nature: the strong interaction, the weak interaction, the electromagnetic interaction, and gravity. However, the first three interactions have already been unified by quantum theory, with only gravity remaining as a separate theory from the others. Therefore, the most important objective of modern physics is to study the theory of quantum gravity. Physicists have found that they can use quantum field theory to study gravity. In this process, we can discover the relationships among quantum entanglement, geometry, and the localization of spacetime, which implies the direction of the development of quantum gravity. We hope to find a breakthrough in the quantization of gravity through quantum entanglement. We then are able to explore the nature of quantum gravity and further understand the nature of spacetime.
