Theoretical physics is often divided into different fields such as particle physics, condensed matter theory, and gravity, depending on the length scale of the logical targets. However, by introducing ideas from quantum information science into the physics of quantum many-body systems, and via their deep connections to quantum gravity, it is becoming clear that what underlies many of these theories is actually the same. This workshop aims to explore the quantum information theoretic connections between these various fields. In particular, we will focus on connections among quantum information, quantum gravity, and both theoretical and experimental quantum matter.
