NTT DOCOMO Tests D-Wave's Quantum to Optimize Mobile Traffic

NTT DOCOMO has implemented quantum optimization from D-Wave Quantum Inc. that has significantly improved mobile network performance. 

Through a pilot project using D-Wave’s annealing quantum computing technology, DOCOMO successfully reduced congestion at base stations by decreasing paging signals during peak usage by 15%. This enhancement allows more terminals to connect during high call volumes, potentially reducing the need for additional infrastructure investment as network demands grow.

The pilot, conducted in specific regions of Japan, demonstrated the efficiency of quantum computing compared to classical methods. D-Wave’s hybrid quantum solver completed complex optimization tasks in just 40 seconds, compared to 27 hours required by traditional solvers. Based on these results, DOCOMO plans to deploy the quantum solution across its Japanese branch offices and explore further applications of quantum optimization in other business areas.

• NTT DOCOMO and D-Wave’s quantum optimization reduced network signal congestion by 15%.
• The quantum solution completed tasks significantly faster than traditional methods, improving network efficiency.
• DOCOMO plans to deploy the technology across Japan and explore further applications in other sectors.

“With D-Wave’s hybrid quantum technology, we aim to set a new standard in the telecommunications industry for operational performance,” said Takatoshi Okagawa, director of research and development strategy at NTT DOCOMO.
