SUMMARY:Seth Lloyd: Sending a photon backwards in time 
CLASS:PUBLIC
DESCRIPTION:Summary \n\nSeth Lloyd\, Massachusetts Institute of Technology 
 \n\nEver since Einstein\, physicists have argued about whether time travel
 \nis consistent with the laws of physics\, and\, if so\, how it might be\n
 accomplished. This talk presents a new theory of time travel based on\nqua
 ntum teleportation. Unlike previous theories\, the theory can be\ntested e
 xperimentally. I report on an experimental realization of the\n'grandfathe
 r paradox': we send a photon a few billionths of a second\nbackwards in ti
 me and have it try to 'kill' its previous self.\n
