 \ntravel 
CLASS:PUBLIC
DESCRIPTION:Summary \n\nDEBBIE LEUNG\, INSTITUTE FOR QUANTUM COMPUTING\n\nW
 e focus on two particular models of closed time like curves.\n\nThe first 
 is Deutsch's 1991 mixed-state-fixed-point model which\nabolishes the grand
 father paradox. The second is due to Bennett and\nSchumacher\, in which th
 e grandfather paradox on certain initial states\nis exploited as a putativ
 e physical mechanism for post-selection.\n
