Abstract

In this work, we investigate the quantum entangled qudits in a trapped three-level ion combining two photons in \(\Lambda \) configuration setting a 12-dimensional Hilbert space. First, the quantum entropy (E) was examined and established as a ”developed measure”. Quantum correlations and entanglement were characterized with E. Second, different rates of the set of Lamb-Dicke Parameter (LDP) values were explored. Third, the entropy values for four optimum scaled times were given as a table. The findings showed when that \(\eta \) increased, the sudden death of entanglement in the trapped ion-phonon system decreased, vice versa. For entangled qudits, such as qubit-qutrit and qutrit-quadrit, the sudden birth of entanglement can be tuned by LDP. We have demonstrated that quantum entanglement is stored in our system. Moreover, the quantity of quantum entropy is maximum degree of \(E=0.706\).
