# Causality violation and nonlinear quantum mechanics

@article{Pienaar2013CausalityVA, title={Causality violation and nonlinear quantum mechanics}, author={Jacques L. Pienaar}, journal={arXiv: Quantum Physics}, year={2013} }

It is currently unknown whether the laws of physics permit time travel into the past. While general relativity indicates the theoretical possibility of causality violation, it is now widely accepted that a theory of quantum gravity must play an essential role in such cases. As a striking example, the logical paradoxes usually associated with causality violation can be resolved by quantum effects. We ask whether the explicit construction of a theory that allows causality violation might in turn… Expand

It is shown that the computational power of the non-causal circuit model is completely characterized by the complexity class UP∩coUP, which implies that classical deterministic closed timelike curves (CTCs) cannot efficiently solve problems that lie outside of that class. Expand

Several novel and distinctive quantum-mechanical effects occur on and near closed timelike lines, including violations of the correspondence principle and of unitarity, and consideration of these sheds light on the nature of quantum mechanics. Expand

It is shown that in a classical limit causal order always arises, which suggests that space-time may emerge from a more fundamental structure in a quantum-to-classical transition. Expand

Remarkably, circuits with access to OTCs are shown to violate Heisenberg's uncertainty principle, allowing perfect state discrimination and perfect cloning of coherent states, and the model is extended to wave packets and smoothly recovers standard quantum mechanics in an appropriate physical limit.
