SUMMARY:Debbie Leung: Computational and Cryptanalytic consequences of time\
 ntravel
CLASS:PUBLIC
DESCRIPTION:DEBBIE LEUNG\, INSTITUTE FOR QUANTUM COMPUTING\n\nWe focus on t
 wo particular models of closed time like curves.\n\nThe first is Deutsch's
  1991 mixed-state-fixed-point model which\nabolishes the grandfather parad
 ox. The second is due to Bennett and\nSchumacher\, in which the grandfathe
 r paradox on certain initial states\nis exploited as a putative physical m
 echanism for post-selection.
