  We investigate the quantum correlation for tripartite entangled states in de
Sitter space. First, we adopt the noisy quantum channel model. In this model,
the expansion effect is represented by an operator sum representation with its
corresponding Kraus operator. This map is shown to be trace-preserving and
completely positive. Second, we analyze the quantum correlation by using the
channel-state correspondence. For a large expansion rate, the tripartite mutual
information has a large negative value, which corresponds to a small magnitude
of bipartite mutual information. We relate this result with the challenge of
recovering information from local measurements.
