Quantum Network Software Advances Bridge Theory and Practice
Researchers are bridging the gap between theoretical quantum network advancements and practical implementation, thanks to software developments. They're using simulators and emulators to model and test protocols before physical deployment, as highlighted in a recent review.
The review found a disparity between theoretical protocols and their real-world application, particularly under dynamic network conditions. However, it also showcased the progress made in software for quantum networks, which is crucial for large-scale quantum communication and computation.
The review categorised software components into infrastructure, logical, and control layers, and proposed a roadmap for building scalable architectures. It covered software for designing protocols like SeQUeNCe, QuISP, and NetSquid, and operating them, focusing on essential control/service plane functions.
Moreover, the review highlighted the necessity of software implementations tailored to quantum systems for deploying quantum networks. Control and management platforms, such as an Operating System for Quantum Network Nodes, are being developed to orchestrate and control quantum network resources and enable application execution.
The review provides a snapshot of the current state of software for quantum networks, demonstrating the foundation being laid for a future quantum internet. Despite persistent gaps between theoretical proposals and realisation, the field is rapidly evolving, with increasing abstraction towards higher-level control platforms, adoption of Software-Defined Networking (SDN) principles, integration with classical networks, standardization efforts, and a focus on automation.
