报告人简介

Xiao-Liang Qi finished his Ph. D. at the Institute for Advanced Study, Tsinghua University in 2007. He did postdoctoral research at Stanford University and UC Santa Barbara, and joined the faculty of Stanford University in 2010. In recent years, he has been mainly working on the relation of quantum information, quantum gravity and quantum many-body physics. He has also worked on topological states of matter and strongly correlated systems.

报告摘要

Holevo information is an upper bound for the accessible classical information of an ensemble of quantum states. In this work, we use Holevo information to investigate the ensemble theory interpretation of quantum gravity. We study the Holevo information in random tensor network states, where the random parameters are the random tensors at each vertex. Based on the results in random tensor network models, we propose a conjecture on the holographic bulk formula of the Holevo information in the gravity case. As concrete examples of holographic systems, we compute the Holevo information in the ensemble of thermal states and thermo-field double states in the Sachdev-Ye-Kitaev model. The results are consistent with our conjecture.
