From relativity\, we know information cannot move faster than the spee d of light. In quantum gravity\, we expect but don't fully understand addi tional constraints\, for instance on how densely information can be stored . Can we develop an understanding of information processing in the context of quantum gravity? Towards doing so\, we consider quantum information wi thin holographic spacetimes\, which have an alternative\, non-gravitationa l\, description. In that context questions about information processing in the presence of gravity can be translated to different questions about qu antum information without gravity. As a specific example\, we study constr aints on computation within a gravitating region\, and use the holographic description to argue that gravity constrains the complexity of operations that can happen inside the region. Along the way\, we are led to new conn ections relating quantum gravity\, position-based cryptography\, quantum s ecret sharing and complexity theory.\n LOCATION:https://researchseminars.org/talk/HET/27/ END:VEVENT END:VCALENDAR
