# Quantum Physics, Fields and Closed Timelike Curves: The D-CTC Condition in Quantum Field Theory

@article{Tolksdorf2016QuantumPF, title={Quantum Physics, Fields and Closed Timelike Curves: The D-CTC Condition in Quantum Field Theory}, author={Juergen Tolksdorf and Rainer Verch}, journal={Communications in Mathematical Physics}, year={2016}, volume={357}, pages={319-351} }

The D-CTC condition has originally been proposed by David Deutsch as a condition on states of a quantum communication network that contains “backward time-steps” in some of its branches. It has been argued that this is an analogue for quantum processes in the presence of closed timelike curves (CTCs). The unusual properties of states of quantum communication networks that fulfill the D-CTC condition have been discussed extensively in recent literature. In this work, the D-CTC condition is…
