Problems with modelling closed timelike curves as post-selected teleportation

arXiv:1107.4675

Abstract

In this comment on S.Lloyd, et al, Phys.Rev.Lett. 106, 040403 (2011), we show that modelling closed timelike curves (CTCs) as post-selected teleportation allows signalling to past times before the creation of the CTC and allows information paradoxes to form.
