Abstract

This workshop brought together experts in classical graph theory and quantum information science to explore the intersection of these fields, with a focus on quantum graph states and their applications in computing, networking, and sensing. The sessions highlighted the foundational role of graph-theoretic structure, such as rank-width, vertex-minors, and hypergraphs, in enabling measurement-based quantum computation, fault-tolerant architectures, and distributed quantum sensing. Key challenges identified include the need for scalable entanglement generation, robust benchmarking methods, and deeper theoretical understanding of generalized graph states. The workshop concluded with targeted research recommendations, emphasizing interdisciplinary collaboration to address open problems in entanglement structure, simulation complexity, and experimental realization across diverse quantum platforms.
