Quantum Information before the Page Time

All in-person attendees must be fully vaccinated, including a booster dose. Individuals must be prepared to present proof of vaccination and booster if asked but will not be required to submit proof. Masks are optional in all indoor spaces.  

This seminar will be presented in-person and on Zoom.

Abstract: Radiation emitted from evaporating black holes is highly mixed, at least for times prior to the so-called "Page time." Usually, the quantum state of the radiation is then treated as void of information. I will discuss two ways in which this early time radiation contains non-trivial quantum information. First, I will characterize (in simple models) to what extent an observer may distinguish different black hole microstates via measurements on their radiation. Then, I will argue that there exists a new time scale prior to the Page time where there is significant entanglement within the radiation. Time permitting, I will discuss relations between these results to thermalization in more general systems and to open problems in quantum information theory.
