摘要：
Quantum entanglement is at the heart of quantum information processing. Ordering the quantum systems due to their entanglement is a popular problem of the field. For two level (qubit) systems of two particles, state ordering has been studied with respect to well-known entanglement measures such as Concurrence, Negativity and Relative Entropy of Entanglement (REE) [1-5]. In this work, we study the state ordering of the three-level quantum systems of two particles with respect to Concurrence and Negativity. In particular, constructing 10K random states and calculating their Concurrences and Negativities, we obtain the orderings of the states and present our results which are interesting when compared to that of two-level systems.
