Quantum entanglement, a fundamental feature of quantum mechanics, has emerged as a powerful
tool that has significantly impacted various areas of physics. Notably, the quantification of entan-
glement through entanglement entropy has played a crucial role in advancing our understanding of
diverse phenomena. In this study, we investigate the presence of quantum entanglement within the
HZZ interaction. Utilizing quantum tomography techniques, we extract the complete spin density
matrix characterizing the HZZ interaction from Monte Carlo simulation data. Subsequently, we
employ the derived spin density matrix to evaluate whether there is quantum entanglement in the
system. Our investigation sheds light on the potential entanglement properties within the HZZ
interaction and offers valuable insights into its quantum characteristics.
