DOCOMO has deployed a second production quantum computing application from D-Wave to optimize mobile network operations in production environments, expanding beyond paging signals to optimize TA-Lists across multiple tracking areas.

This latest deployment follows the first production effort, which focused on paging signals within tracking areas, and now targets optimization of tracking area lists across several areas.

Forward-looking statements acknowledge risks and uncertainties about projections and investments associated with the deployment.

Leaders emphasize that applying quantum optimization to real-world, resource-constrained telecom operations is meaningful and is being integrated into network planning and daily operations.

In tests with 333 base stations, three TA-Lists and nine tracking areas, the optimization completed in about five minutes and the results are now used in planning and day-to-day operations.

The new application achieved a 65.3% reduction in daily peak location registration signals and a 7.0% reduction in paging signals, lowering overall signaling load across tracking area lists.

DOCOMO is Japan’s largest mobile operator with more than 93 million subscriptions, and D-Wave provides both annealing and gate-model quantum computing platforms.

DOCOMO’s senior manager Hiroshi Kawakami notes the approach demonstrates quantum optimization addressing multiple network aspects and more efficient use of infrastructure.

The achievement fits within broader efforts to apply annealing quantum computing to practical, complex network optimization tasks.

DOCOMO is highlighted as a leading example for telecom operators adopting quantum technology to improve real-world network efficiency.

D-Wave CEO Dr. Alan Baratz says the results show production-ready quantum adoption capable of handling increasingly complex operational challenges in telecom networks and emphasizes annealing’s role in resource-constrained environments.
