Information Theory SG by Dr. Yukimi Goto on December 23, 2020

This week, Dr. Yukimi Goto gave us an introduction to the Lieb-Robinson bound. After reviewing several important preliminaries, such as Liouvillians for open quantum systems, she discussed the Lieb-Robinson bound, which is a theorem for the bound on speed of information propagation. She then explained two notable applications of the bound, i.e., correlation decay and the entanglement area law for a gapped ground state in isolated quantum systems. We thank Goto-san for her great talk!
