A Measurement Plane for Quantum Networking
The core problem
Quantum networking testbeds are increasingly deployed to validate entanglement distribution, coincidence measurements, and other quantum communication primitives. However, these testbeds typically inherit the architectural planes of classical networks—data, control, and management—which are not designed to coordinate distributed measurements or aggregate experimental data across heterogeneous quantum devices. As a result, researchers must manually configure instruments, synchronize remote nodes, and collect results, which limits scalability and reproducibility.
The authors identify a clear gap: there is no distinct plane dedicated to measurement coordination and data collection in quantum networking. Existing planes either focus on forwarding quantum states (data plane), configuring devices (control plane), or monitoring classical network health (management plane). None provides a unified abstraction for orchestrating experiments that span multiple nodes and device types.
To address this gap, the paper proposes the **Measurement Plane**, a dedicated architectural plane that complements rather than replaces or extends the existing pipelines. The contribution is a distributed frame
Innovation
The framework was evaluated on a two-node quantum networking testbed connected by an optical network. The Measurement Plane successfully coordinated the remote nodes to execute two types of experiments: coincidence measurement and polarization entanglement distribution.
For the entanglement distribution experiment, the framework achieved visibility interference of up to **98%**. This high visibility indicates that the distributed measurement coordination did not introduce significant errors or decoherence, and that the automated synchronization and feedback mechanisms were effective. The coincidence measurement experiments further demonstrated the framework's ability to collect and aggregate data from multiple devices in a distributed setting.
The evaluation also showed that the framework enabled **online measurement and feedback**, meaning that measurement results could be used to adjust experimental parameters in real time. This capability is crucial for optimizing quantum experiments, where environmental fluctuations and device drift can degrade performance. By automating the coordination and data collection, the framework significantly reduced manual configuration and executi
Why it matters
The Measurement Plane addresses a critical gap in quantum networking testbeds by introducing a dedicated plane for measurement coordination and data collection. Unlike existing approaches that extend the data, control, or management planes, this framework is designed from the ground up to handle the unique requirements of distributed quantum experiments: precise synchronization, heterogeneous device integration, and online feedback.
The four-layer architecture provides a clean separation of concerns. The application layer allows researchers to define experiments without worrying about device-specific details. The experiment coordination layer handles the distributed execution, while the capability and resource agent layers abstract the underlying hardware. This separation is essential for scalability, as new devices can be integrated by adding resource agents without modifying higher layers.
The use of containerized microservices and publish–subscribe messaging ensures that the framework is modular, extensible, and resilient. The publish–subscribe model is particularly well-suited for quantum experiments, where measurement events are asynchronous and may need to be broadcast to multiple consumers.
The validation on a two-node setup with 98% visibility interference demonstrates the framework's effectiveness. However, the evaluation is limited to a small-scale testbed. Future work should explore scaling to larger networks with more nodes and diverse quantum devices. Additionally, the framework's performance under realistic network conditions, such as variable latency and packet loss, should be assessed.
Despite these limitations, the Measurement Plane represents a significant step toward automated, reproducible quantum networking experiments. By reducing manual effort and enabling online feedback, it can accelerate the development of quantum communication protocols and applications. The framework's design principles—layered abstraction, microservices, and publish–subscribe—are likely to be applicable to other distributed scientific instruments beyond quantum networking.
