Abstract

Quantum communications promises major changes in today’s communication networks by sending qubits over long distances. These qubits enable large-scale quantum computing or information-theoretically secure distribution of symmetrical keys. One of the main enablers is quantum teleportation, which makes sending quantum information between two nodes possible even when they are far apart. From these nodes, one can build a larger quantum network, but due to the nature of quantum physics, certain tasks that are well understood in classical networks, such as routing, cannot be handled in a similar way. Our work focuses on modifying a previously created model for a ring-like quantum network and assessing the effect of introducing a new node type. Our results show that this node can alter properties of the underlying network. We also look at the possibilities of modeling the capacity of the network as well as the availability of the newly introduced edges, which open interesting questions for future research.
