Description
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 entanglement 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.
