Abstract: Many studies have been published in quantum communication focused on the natural law of communication depend on the entanglement between the Qubit. This review paper focused on the architecture (p2p, multi nods to a single node and multi nodes to multi nodes), this paper has shown when connected two nodes they use entanglement method, for multi-users must connect by another type of connecting such as multi-quantum lines links such as in fixed network when connected one server two multi nodes. p2p method is best for security purpose such as in peer to a server connected for login authentication or for sending the encrypted password, multi-users(nodes) method is best for security purpose to quantum key distribution, the other methods connect two nodes (p2p) for sending and receiving data such as in quantum satellite, quantum radar, and quantum sensor. Another different type of communication inside of the quantum computer established by using quantum gates.
