Theoretical description and experimental simulation of quantum entanglement near open time-like curves via pseudo-density operators

Description of a qubit following an open time-like curve usually incurs into conceptual problems such as violation of entanglement monogamy. Here, the authors show how to use the formalism of pseudo-density operators to describe such a process, showing a proof-of-principle experimental simulation.
