NTT DOCOMO, Japan’s largest mobile phone operator, has successfully demonstrated a 15% improvement in mobile network performance using quantum optimization technology developed by D-Wave Quantum Inc., a leader in quantum computing systems and software. The pilot project, which utilized D-Wave’s annealing quantum computing solutions, reduced congestion at base stations by decreasing paging signals during peak calling times. This breakthrough has the potential to increase efficiencies and lower infrastructure costs for mobile network operators.
The solution was tested in certain areas of Japan, including Tokai, Chugoku, and Kyushu regions, and showed that D-Wave’s hybrid solver could complete a task in 40 seconds that would take a general-purpose solver 27 hours. Takatoshi Okagawa, director of research and development strategy at NTT DOCOMO, stated that the company anticipates its quantum optimization strategy will further refine network efficiency, allowing it to maintain high-quality service without additional infrastructure investments as network traffic increases. Dr. Alan Baratz, CEO of D-Wave, emphasized that this successful pilot demonstrates the capability of today’s quantum technologies to solve complex optimization problems in the telecommunications industry.
Quantum Optimization Technology Improves Mobile Network Performance
NTT DOCOMO, Japan’s largest mobile phone operator, has successfully demonstrated the potential of quantum optimization technology to improve mobile network performance by 15%. In collaboration with D-Wave Quantum Inc., a pioneer in quantum computing systems, software, and services, DOCOMO utilized D-Wave’s annealing quantum computing solutions to reduce congestion at base stations during peak calling times. This achievement has significant implications for the telecommunications industry, as it could lead to increased efficiencies, lowered infrastructure costs, and enhanced customer satisfaction.
The pilot project focused on optimizing base station tracking areas, which are small geographical regions that collectively send paging signals and process extensive historical data on device movements between stations. By leveraging D-Wave’s hybrid-quantum technology, DOCOMO was able to predict future movement patterns and determine the best combination of base stations to re-establish connections as devices move between tracking areas. The results showed that quantum optimization led to a 15% reduction in paging signals, allowing approximately 1.2 times more terminals to be connected during periods of high call volume.
This expanded bandwidth for base station resources has the potential to greatly reduce congestion, enabling DOCOMO to maintain quality network traffic flow even during heavy usage. The successful pilot demonstrates the feasibility of applying quantum optimization technology to complex operational problems in the telecommunications industry. As Takatoshi Okagawa, director of research and development strategy at NTT DOCOMO, noted, “We anticipate that our quantum optimization strategy will further refine network efficiency, allowing us to maintain high-quality service without additional infrastructure investments as network traffic increases.”
Expanding Quantum Optimization Across Business Units
Following the successful pilot, DOCOMO plans to deploy the annealing quantum computing solution into production at branch offices across Japan. The company is also exploring opportunities to apply quantum optimization across its business units, including finance, retail, traffic and logistics, and construction. This expansion has significant implications for the broader adoption of quantum optimization technology in various industries.
The potential applications of quantum optimization are vast, ranging from optimizing supply chains and logistics to enhancing financial modeling and cybersecurity. As DOCOMO continues to explore the possibilities of quantum optimization, it may uncover new opportunities to create value-added services that change the way people live and work. The successful pilot project serves as a testament to the growing importance of quantum computing in driving innovation and competitiveness across industries.
