This thesis treats networks providing quantum computation based on distributed paradigms. Compared to architectures relying on one processor, a network promises to be more scalable and less fault-prone. Developing a distributed system able to provide practical quantum computation comes with numerous challenges, each of which need to be faced with careful analysis in order to create a seamless integration of multiple engineered components.
In accordance with hardware technologies, currently under development worldwide, telegates represent the fundamental inter-processor operations. Each telegate consists of several tasks: i) entanglement generation and distribution, ii) local operations, and iii) classical communications. Entanglement generation and distribution is an expensive resource, as it is time-consuming. The primary contribution of this thesis lies in the extensive analysis of some complex scenarios of general interest. We propose numerical models that help to identifythe interdependence between computation and communication. With the support of some of the best tools for reasoning -- i.e. network optimization, circuit manipulation, group theory and ZX-calculus -- we lay out new perspectives on the way a distributed quantum computing system should be developed.

本論文探討基於分散式範式的量子計算網路。與依賴單一處理器的架構相比，網路承諾具有更好的可擴展性和較低的故障率。開發一個能夠提供實用量子計算的分散式系統面臨許多挑戰，每一個挑戰都需要透過仔細分析來解決，以實現多個工程組件的無縫整合。
根據目前全球正在開發的硬體技術，telegate 代表了基本的處理器間操作。每個 telegate 包含幾個任務：i) 纏結生成與分配，ii) 本地操作，以及 iii) 古典通訊。纏結生成與分配是一項昂貴的資源，因為它耗時。這篇論文的主要貢獻在於對一些具有普遍興趣的複雜情境進行深入分析。我們提出數值模型，幫助識別計算與通訊之間的相互依賴性。在一些最佳推理工具的支持下——即網路優化、電路操作、群論和 ZX-calculus——我們提出了關於如何開發分散式量子計算系統的新視角。
