Special Physics Seminar

Quantum Information and Quantum Gravity

Ning Bao

Brookhaven National Laboratory

There has been tremendous progress in recent years in the study of quantum gravity via the lens of quantum information science. In this talk, I will give an overview of the basic techniques of both areas, as well as some exciting new ones, highlighting some work that I have been able to complete in this area: first, the classification of what states are allowed to be dual to semiclassical spacetimes via the Ryu-Takayanagi formula and generalizations thereof, and second, the use of computational complexity to give an existence proof to non-anthropic explanations for the size of the cosmological constant. Throughout, I will highlight exciting further directions that I have pursued/am interested in pursuing.
