Item 7.01 Regulation FD Disclosure. On August 18, 2026, D-Wave Quantum Inc. (“D-Wave”) and NTT DOCOMO, INC. (“DOCOMO”), Japan’s largest mobile operator with more than 93 million subscriptions, announced that DOCOMO has deployed a second D-Wave-powered quantum computing application in production. The new application reduced location registration signals generated when devices cross tracking area list (“TA-List”) boundaries by 65.3% at the daily peak while also reducing paging signals by 7.0%, lowering network signaling load and improving operational efficiency. TA-Lists group geographic areas within a mobile network and must be carefully optimized to reduce signaling load while maintaining network performance and connectivity. The deployment expands DOCOMO’s production use of quantum computing to a broader network optimization challenge. While its first D-Wave-powered application reduced paging signals within tracking areas, the new application optimizes TA-Lists across multiple tracking areas, balancing location registration and paging signals that typically move in opposite directions. In a representative problem spanning 333 base stations, three TA-Lists and nine tracking areas, the application completed the optimization in approximately five minutes, with the results incorporated into DOCOMO’s network planning and day-to-day operations. According to D-Wave’s CEO, Dr. Alan Baratz, these results demonstrate how D-Wave’s annealing quantum computing technology can help operators improve network performance and efficiency today.
