Description
Summary:We investigated the entanglement in a diluted magnetic semiconductor quantum dot, crucial for quantum technologies. Despite their potential, these systems exhibit low extraction rates. We explore self-assembled InGaAs quantum dots, focusing on entanglement between them based on spin states. Our analysis involves defining wavefunctions, employing density matrix operators, and measuring entanglement entropy. Numerical assessments reveal few promising pairs among various quantum dot combinations that exhibit significant entanglement. Additionally, this work discusses theoretical developments and statistical evaluations of entanglement in diluted magnetic semiconductor quantum dots, providing insights into their potential for quantum applications.
