  The traditional formalism of non-relativistic quantum theory allows the state
of a quantum system to extend across space, but only restricts it to a single
instant in time, leading to distinction between theoretical treatments of
spatial and temporal quantum correlations. Here we unify the geometrical
description of two-point quantum correlations in space-time. Our study presents
the geometry of correlations between two sequential Pauli measurements on a
single qubit undergoing an arbitrary quantum channel evolution together with
two-qubit spatial correlations under a common framework. We establish a
symmetric structure between quantum correlations in space and time. This
symmetry is broken in the presence of non-unital channels, which further
reveals a set of temporal correlations that are indistinguishable from
correlations found in bipartite entangled states.
