A Control Architecture for Entanglement Generation Switches in Quantum Networks

Entanglement between quantum network nodes is often produced using intermediary devices - such as heralding stations a resource. When scaling networks to many nodes, requiring dedicated device for every pair of introduces high costs. Here, we propose cost-effective architecture connect via central hub called an Generation Switch (EGS). The EGS allows multiple be connected at fixed resource cost, by sharing the resources needed make entanglement. We algorithm Rate Control Protocol (RCP) which moderates level competition access hub's sets users. proceed prove convergence theorem rates yielded algorithm. To derive work in framework Network Utility Maximization (NUM) and use theory Lagrange multipliers Lagrangian duality. Our lays groundwork developing control architectures compatible with other types hubs well system models greater complexity.
