D-Wave Quantum Inc. (D-Wave) and NTT DOCOMO Inc. (DOCOMO) have announced a successful quantum optimization pilot that is set to improve mobile network performance.
By using D-Wave's quantum computing solutions, DOCOMO was able to reduce congestion at base stations during peak calling times by 15%, potentially leading to cost savings. The company plans to implement this hybrid-quantum solution in its Japanese branch offices soon.

The technology optimizes base station tracking areas by sending paging signals and analyzing historical data on device movements. This allows DOCOMO to predict movement patterns and determine the best base stations to connect devices as they move between different areas.
In pilot tests in Japan, D-Wave's hybrid solver completed tasks much faster than traditional methods, showing a 15% reduction in paging signals. This increased bandwidth for base stations can significantly reduce congestion and maintain network quality during high usage periods.
NTT DOCOMO's Director of Research and Development Strategy, Takatoshi Okagawa, believes that quantum optimization will enhance network efficiency without the need for additional infrastructure investments.
D-Wave's CEO, Dr. Alan Baratz, sees this pilot as a sign that quantum technologies can solve complex optimization problems for telecommunications companies.
After the successful pilot, DOCOMO plans to implement the quantum computing solution in its branch offices and explore its application in other business units like finance, retail, traffic, logistics, and construction.
