In this thesis, I explore whether it is possible to build a unified Quantum Internet architecture that supports different types of quantum repeaters -- especially the two most distinct and seemingly incompatible ones: memory-based quantum repeaters and all-photonic, memoryless repeaters. These technologies have traditionally been developed with the aim of becoming the single dominant solution, but I ask: Can they work together in the same network? What kind of architecture would support both? And how can simulation help us understand what is needed to manage such a network at scale? To address these questions, I propose an architecture based on an existing recursive network design and programmable RuleSet-based protocols that can coordinate diverse hardware components. I introduce a new emitter-photon building block to bridge memory-based and all-photonic segments, and show how classical networking abstractions can be extended to manage quantum operations. While I have developed a simulation tool grounded in these architectural principles and validated it against existing simulators and analytical models, a full-scale investigation of the resource trade-offs and performance implications remains future work. Nevertheless, the results so far suggest that a unified, heterogeneous quantum network is not only possible but increasingly practical with current technologies -- though ongoing experimental progress will be essential to fully realize this vision.

Internet-scale quantum repeater networks will be heterogeneous in physical technology, repeater functionality, and management.The classical control necessary to use the network will therefore face similar issues as Internet data transmission.Many scalability and management problems that arose during the development of the Internet might have been solved in a more uniform fashion, improving flexibility and reducing redundant engineering effort.Quantum repeater network development is currently at the stage where we risk similar duplication when separate systems are combined.We propose a unifying framework that can be used with all existing repeater designs.We introduce the notion of a Quantum Recursive Network Architecture, developed from the emerging classical concept of recursive networks, extending recursive mechanisms from a focus on data forwarding to a more general distributed computing request framework.Recursion abstracts independent transit networks as single relay nodes, unifies software layering, and virtualizes the addresses of resources to improve information hiding and resource management.Our architecture is useful for building arbitrary distributed states, including fundamental distributed states such Bell pairs and GHZ, W, and cluster states.
