Alexey Urivskiy (Infotecs) Quantum key distribution protocols for quantum networks based on trusted nodes

We consider design principles of network quantum key distribution protocols based on the usage of trusted intermediate nodes. Quantum networks in practice are not able to produce quantum keys for an arbitrary pair of nodes. This implies the concept of the so-called quantum-protected keys. We investigate possible design approaches to establishing uantum-protected keys in networks of arbitrary topologies. Security of and level of trust to those keys are discussed as well as performance of the protocols.
