We investigate quantum correlations in time in different approaches. We assume that temporal correlations should be treated in an even-handed manner with spatial correlations. We compare the pseudo-density matrix formalism with several other approaches: indefinite causal structures, consistent histories, generalised quantum games, out-of-time-order correlations(OTOCs), and path integrals. We establish close relationships among these space-time approaches in non-relativistic quantum theory, resulting in a unified picture. With the exception of amplitude-weighted correlations in the path integral formalism, in a given experiment, temporal correlations in the different approaches are the same or operationally equivalent.

Detecting and quantifying non-Markovianity via quantum direct cause
Pseudo-density-matrix measures detect eternal CP-indivisibility that temporal steering, trace distance, and entropic measures miss, and a new continuous-time causality measure generalizes the Rivas-Huelga-Plenio witness.
