How should we deal with the closed timelike curves (CTCs) in quantum mechanics? The CTC has many paradoxical situations like the grandfather paradox. From the viewpoint of information processing, I will present the grandfather paradox. Furthermore, I will review the Deutsch and our answers. Our answer is called the post-selected CTC based on the idea of quantum teleportation. On considering the causality, I would like to discuss about the post-selected CTC.
