D-Wave Quantum is trading at $22.25 (up 4%) in pre-market, extending a strong multi-day rally following a major technical milestone.

  • The move follows an August 5 announcement of a quantum error-correction breakthrough published in the journal Nature, which is seen as a critical step toward practical, fault-tolerant gate-model quantum computing.
  • The stock's strength is primarily driven by company-specific optimism and ongoing investor interest in quantum and AI hardware names, outperforming broader mixed indices.
  • This price action continues a significant recovery trend for the stock since hitting lows in late July.
