Distributed quantum information in networks is paramount for global secure quantum
communication. Moreover, it finds applications as a resource for relevant tasks, such as …

We consider entanglement-based quantum networks, where multipartite entangled resource
states are distributed and stored among the nodes and locally manipulated upon request to …

Lie groups, and therefore Lie algebras, are fundamental structures in quantum physics that
determine the space of possible trajectories of evolving systems. However, classification and …

A classical switch or router determines which of several inputs to the device passes through
the output. In analogy, a quantum switch that coherently links the input to a superposition of …

Quantum information processing architectures typically only allow for nearest-neighbor
entanglement creation. In many cases, this prevents the direct generation of GHZ states …

In quantum computing and quantum information processing, graph states are a specific type
of quantum states which are commonly used in quantum networking and quantum error …

One of the great promises of quantum technology is the development of quantum networks,
which will allow global distribution of entanglement for tasks such as distributed quantum …

Local sets, a graph structure invariant under local complementation, have been originally
introduced in the context of quantum computing for the study of quantum entanglement …
