  In this study, we investigate the behavior of entanglement properties in the
QCD phase diagram using holographic Einstein-Maxwell-Dilaton (EMD) models. We
consider two representative holographic QCD models and examine various
entanglement measures, including entanglement entropy, conditional mutual
information, and entanglement of purification. We find that the entanglement
entropy obtained using the direct UV-cutoff renormalization method shows
significant dependence on the specific model being used. However, the outcomes
of other non-divergent entanglement measures, such as cutoff-independent
entanglement entropy, conditional mutual information, and entanglement of
purification, exhibit congruence in our calculations. When we focus
specifically on the temperature range below $300$ MeV, we observe a similar
behavior among the three entanglement measures. This may suggests that within
this temperature range, the entanglement of QCD matter decreases with
increasing temperature. Additionally, we observe distinct phase transition
behaviors of entanglement properties at the critical end point (CEP) and
first-order phase transitions. This observation highlights the potential of
entanglement properties as effective order parameters for QCD matter phase
transitions.
