报告内容简介：
In physics, the principle of locality says that each phenomenon is influenced directly by the local surroundings. This could be
translated to a simple mathematical statement of no wisdom at all. Nevertheless, with extravagant description of the obvious truth, or
fascinating explanation of absurdity, the principle may become a big law/theory/theorem or a paradox to shake your body/mind. Here, I will
give an expository talk in the settings of direct sums and tensor products as related to quantum information theory.
