- Abstract: 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
many challenges, each of which need to be faced with careful analysis in order
to create a massive integration of several components properly engineered. In
accordance with hardware technologies, currently under construction around the
globe, 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 main contribution of this thesis is on the definition of
compilers that minimize the impact of telegates on the overall fidelity.
Specifically, we give rigorous formulations of the subject problem, allowing us
to identify the inter-dependence 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 found
new perspectives on the way a distributed quantum computing system should
evolve.
