Abstract
Quantum computing and quantum communication will have a great impact on our world. A quantum Internet will enable applications that are fundamentally out of reach for the classical Internet, in particular security applications, due to the inherent characteristics of quantum physics that allow protecting data during the exchange of quantum information or in the sharing of entangled quantum state between two or more parties. However, quantum signals are weak and very fragile, and cannot be copied or amplified. To exchange data over long distances, in topologically complex networks, built on heterogeneous technologies and managed by many independent organizations, quantum repeaters are required. In order to enable widespread use and application development, it is essential to develop methods that allow quantum protocols to connect to the underlying hardware implementation transparently. Classically, this is achieved by a series of layered protocols, such as the TCP/IP stack, that provide an abstraction that ultimately allows application protocols to exchange data between two end nodes without having to know any details on how this connection is actually realized. Few approaches for network stack presently exist for a quantum Internet, and only some basic elements have been noted. To fully unleash the potentials of quantum computing, several new challenges and open problems need to be addressed. From a data forwarding perspective, the routing problem is crucial. This project's main objective is to develop algorithms and routing protocols that ensure the discovery of the best route in different quantum network topologies, enhancing the opportunities for quantum communication between an arbitrary pair of quantum devices, using the approach of performing such communication as transformations performed on virtual quantum link graphs. It is planned to develop and analyze the solution, both in the context of conventional quantum networks and software-defined quantum networks. After due mathematical analysis, it is intended to use event simulation as the complementary approach to evaluate the developed algorithms and protocols. (AU)
