D-Wave Quantum Inc. filed a Form 8-K on August 18, 2026, disclosing that NTT DOCOMO, INC. has deployed a second D-Wave-powered quantum computing application in production, targeting mobile network signaling optimization.

Key Highlights

  • Second production deployment: DOCOMO has deployed a second D-Wave-powered quantum computing application in production, expanding beyond its first application.
  • Location registration signals reduced 65.3%: The new application reduced location registration signals at the daily peak by 65.3% at TA-List boundaries, according to the filing.
  • Paging signals reduced 7.0%: The application also reduced paging signals by 7.0%, according to the filing.
  • Representative problem scale: In a representative problem, the application spanned 333 base stations, three TA-Lists, and nine tracking areas.
  • Optimization completed in approximately five minutes: Results were incorporated into DOCOMO's network planning and day-to-day operations.
  • DOCOMO scale: The filing describes DOCOMO as "Japan's largest mobile operator with more than 93 million subscriptions."

D-Wave and DOCOMO Expand Quantum Network Optimization to TA-List Management

According to the Form 8-K filed by D-Wave Quantum Inc. (NASDAQ:QBTS) on August 18, 2026, the company and NTT DOCOMO, INC. announced that DOCOMO has put a second D-Wave-powered quantum computing application into production use. The new application focuses on optimizing tracking area lists, referred to in the filing as "TA-Lists," which the filing describes as groupings of geographic areas within a mobile network that "must be carefully optimized to reduce signaling load while maintaining network performance and connectivity."

The filing states that the new application reduced location registration signals generated when devices cross TA-List boundaries by 65.3% at the daily peak, while also reducing paging signals by 7.0%. The disclosure notes that these two signal types "typically move in opposite directions," making simultaneous reduction a network planning challenge. This deployment differs from DOCOMO's first D-Wave-powered application, which the filing says "reduced paging signals within tracking areas"; the new application instead optimizes TA-Lists "across multiple tracking areas."

In a representative problem described in the filing, the application covered 333 base stations, three TA-Lists, and nine tracking areas, completing the optimization in approximately five minutes. The filing attributes the following statement 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." The filing notes that the information is furnished under Regulation FD and is not deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934.
