讲座内容：

In this talk, I introduce several Bell type inequalities and the corresponding maximal quantum mean values(MQMV). Based on the MQMV and upper bounds of the norms of Bloch vectors, we further discuss the trade-off relation for multipartite quantum systems. The local filtering operations are also considered to reveal hidden Bell nonlocality. I will also give a short introduction to quantum algorithms such as the HHL, quantum Karczmarz algorithms，VQA for Poisson equation，Quantum SVM based on Trainable Kernal function et al.
