Resource access represents one of the fundamental challenges in distributed systems, as multiple nodes often compete for limited communication opportunities. For example, WiFi users sharing a common radio channel typically achieve only moderate efficiency. Classical random-access protocols such as Slotted ALOHA and contention-based schemes such as Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA), rely on probabilistic transmission attempts and backoff mechanisms. As a result, both approaches still suffer from collisions, idle periods, and reduced throughput under increasing contention. To address these limitations, this paper simulates a quantum entanglement–based medium access mechanism to demonstrate how shared entanglement can enhance efficiency in distributed resource access. We present a general model involving multiple nodes with adjustable transmission priorities, achieving high efficiency while completely eliminating resource collisions. A comparative evaluation is conducted between Slotted ALOHA, CSMA/CA, and the entanglement-based approach. The results show that the proposed quantum MAC achieves significantly higher throughput and zero collisions compared to classical protocols. Furthermore, the required entangled states can be established in a distributed manner, highlighting the practical feasibility of the proposed solution.
