DESCRIPTION:Quantum information science was initially motivate
 d by questions about information processing. For e
 xample\, what are the consequences of quantum mech
 anics for computation? Or for cryptography? More r
 ecently\, quantum information has also become a pe
 rspective through which we can study questions in 
 theoretical physics more broadly\, including in co
 ndensed matter and quantum gravity. While quantum 
 information considers the constraints of quantum m
 echanics\, there are additional constraints on inf
 ormation implied by relativity. In particular\, it
  is impossible to send information faster than the
  speed of light. In this talk\, I consider constra
 ints on information processing imposed by quantum 
 mechanics and relativity together\, and the conseq
 uences of these constraints for quantum gravity. D
 oing so reveals novel aspects of how gravitational
  degrees of freedom can be recorded into a quantum
  mechanical system\, and how an extra dimension ca
 n be recorded into ``holographic'' field theories.
