Analyzing of Quantum Entanglement with Concurrence in the Deep Lamb-Dicke Regime

Abstract

The entangled states of three-level of trapped ion and two phonons (into coherent state) in Λ configuration forming a Hilbert space of 12-dimensional (D) are analyzed. The concurrence is considered "such as a quantum measure" in trapped ion-coherent state system. Four values of Lamb-Dicke parameter (LDP), = 0.005, 0.07, 0.08 and 0.09 are investigated by the worths of concurrence. We demonstrate that as is increased, sudden birth of entangled states in the system is increased. Thus, establishing of entangled states can be tuned by LDP.

In the Context of Time-Independent Parameters in Two Quantum Systems: Quantum Entanglement and Correlations With Negativity Measurement

“…The presence of long lived entanglement in trapped ion and phonons system have been recognized by Figure 4. We explore with N that measurement degrees have a flash crop entangled state up in parallel to raising and this is in comparison to the previous observations [6,27,28,29,30,31].…”
