Comcast Corporation, Classiq and Advanced Micro Devices completed a joint trial that applied quantum algorithms to improve Internet routing resilience. The project focused on identifying independent backup paths during routine network maintenance, a combinatorial optimization problem that grows exponentially as networks scale. The companies said the trial demonstrated that quantum techniques, combined with high-performance classical computing, can address real-world network design challenges.
The trial addressed a key operational scenario: when operators take a network site offline for scheduled maintenance, they must ensure traffic can reroute seamlessly if a second site fails during that window. Identifying unique, low-latency backup paths that remain resilient to simultaneous link failures becomes computationally complex in large-scale networks. The team tested quantum algorithms to determine whether they could identify such paths in real time across change management scenarios.
The project combined execution on quantum hardware with GPU-accelerated simulations using AMD Instinct GPUs to extend computational capacity beyond current qubit limits. Engineers iterated in simulation environments and validated performance with runs on quantum hardware. Classiq provided its quantum software platform to model and implement optimized circuits across different backends. “Our results have shown that quantum computing for network optimization isn’t theoretical – it’s practical, scalable, and grounded in the needs of our customers,” said Elad Nafshi, Chief Network Officer, Comcast Connectivity and Platforms.

🌐 Analysis: Telecom operators continue to explore quantum computing for optimization use cases such as routing, spectrum allocation and network design. This trial reflects a broader industry trend in hybrid quantum-classical workflows, where GPU-accelerated simulation platforms bridge the gap until larger-scale, fault-tolerant quantum systems become commercially viable. AMD’s involvement aligns with its strategy to position high-performance compute platforms as foundational infrastructure for emerging quantum workloads.
