  7. Abstract:
  8. Entanglement is a defining characteristic distinguishing quantum systems from their classical counterparts. Since previous research has proven this phenomenon is the main reason for supremacy of quantum information processing protocols over classical information processing, the study of quantum entanglement has increasingly garnered more importance. On the other hand, our comprehension of multi-body and many-body systems continues to evolve. To understand these systems better, it is necessary to research their crucial feature, entanglement. In this study, after introducing multipartite absolutely maximally entangled states, their statistical distribution will be explored. This task will be done using analytical calculations and computer simulations. Moreover, in this text, we will be presented to another class of multipartite quantum states which has been introduced recently. These states are named planar maximally entangled states. Later, using methods of statistical mechanics, the differences of these states with absolutely maximally entangled states will be shown. Finally, we will probe the significance of these states and the importance of statistically studying them
