• Quantum networks have evolved from small-scale experiments to metropolitan-scale demonstrations, yet scalability remains a critical hurdle.

Argonne National Laboratory has launched a project to advance scalable quantum communications, according to an update on the lab’s website.

The initiative — called InterQnet — aims to confront many of the challenges of quantum networks through a comprehensive, systems-oriented approach. InterQnet focuses on improving devices, error handling and network architecture.

Quantum networks have evolved from small-scale experiments to metropolitan-scale demonstrations, yet scalability remains a critical hurdle, the team indicates. The increasing number of nodes, the distances between them, the diversity of applications, and the growing number of users compound the complexity of these networks. InterQnet addresses these challenges through a two-pronged strategy, integrating a systems approach into scalable quantum communications.

The team reports that the first prong, known as InterQnet-Achieve, emphasizes the practical realization of a heterogeneous quantum network. A heterogenous quantum communication network that involves different types of quantum systems or platforms that can interoperate with each other. In this context, the network involves constructing and integrating a prototype first-generation quantum repeater with an error mitigation scheme and a centralized automated network control system. The aim is to enable seamless quantum communications between two different quantum platforms, facilitated by a third platform functioning as a repeater node.

Argonne National Laboratory researchers suggest InterQnet-Achieve’s approach is poised to bridge the gap between disparate quantum systems, enhancing the robustness and reliability of quantum communications. If successful, a centralized control system could streamline operations and mitigate errors.

The second prong, InterQnet-Scale, focuses on a systems study of architectural choices for scalable quantum networks. The approach could lead to futuristic models of quantum network devices, advanced error correction schemes and entanglement protocols. Argonne researchers plan to conduct complex simulations combining these architectural choices within SeQUeNCe, a quantum network simulator under development at the laboratory.

By leveraging SeQUeNCe, InterQnet-Scale aims to explore and validate various architectural configurations, pushing the boundaries of what is possible in quantum network design. This strategic approach is designed to inform future implementations, ensuring that the networks are not only scalable but also efficient and resilient.

Overall, Argonne is laying out a comprehensive strategy that demonstrates importance of a holistic approach to quantum network development.

Argonne National Laboratory is a multidisciplinary science and engineering research center located near Chicago, Illinois, operated by the U.S. Department of Energy. It conducts leading-edge research in areas such as energy, materials science, biological systems and national security, aiming to solve some of the most pressing national challenges and drive technological innovation.
