D-Wave to Buy Quantum Circuits for $550 Million to Speed Error-Corrected Gate-Model Push

The combination pairs D-Wave’s annealing and cloud platform with Quantum Circuits’ dual-rail technology to pursue an initial system targeted for 2026.

Overview

  • D-Wave said the deal totals about $300 million in stock and $250 million in cash.
  • Management projects the acquisition will accelerate work toward a scaled, fully error-corrected gate-model computer, with an initial dual-rail system expected in 2026.
  • Recent results show revenue acceleration, including roughly $3.74 million in Q3 2025 and about $24 million over the past 12 months.
  • The company remains deeply unprofitable, with heavy operating expenses and recent quarters affected by large non-cash warrant-related charges.
  • D-Wave reported roughly $819 million in cash, observers estimate 2–3 years of runway, and analysts both praised the strategic fit and cautioned about valuation, integration, and technical risks.
