  We use the quantumcorrelation of both logarithmic negativity andmutual
information between a qubit and a relativistic boson to analyze the dynamics of
Universe expansion. These dynamical quantum correlations can encode the
information about underlying spacetime structure, which suggests a promising
application in observational cosmology. We find that the dynamics of both
logarithmic negativity and mutual information between the qubit and the boson
are very similar. They decrease monotonically with the growth of the expansion
volume and the expansion rate. Smaller momentum and medium-sized mass of boson
are more favourable for extracting the information about history of Universe
expansion. The quantum correlation between the qubit and the antiboson however
has very different behavior: the logarithmic negativity is always zero and the
mutual information can be generated through the expansion of Universe. Smaller
momentum and medium-sized mass of antiboson are beneficial for the production
of mutual information. Finally, the trigger phenomenon and conservation for
mutual information are witnessed.
