Summary

• What is new: Introduction of a quantum switch for GKP-qubit-based quantum networks, employing multiplexed entanglement link generation and all-photonic storage, optimized for maximized sum throughput and fairness in entanglement rates.
• Why this is important: Creating an efficient architecture for quantum networks that overcomes the limitations of finite squeezing in GKP code preparation and homodyne detection inefficiencies.
• What the research proposes: A quantum switch architecture that utilizes multiplexed GKP-qubit-based entanglement link generation with clients, supplemented by all-photonic storage and a multi-client entanglement-ranking-based link matching protocol.
• Results: Illustration of increased entanglement rates and optimal resource allocation in an exemplary data center network scenario, showing the switch’s effectiveness in improving quantum network connectivity and throughput.
