2026 has been marked by periods of significant momentum for quantum computing giant D-Wave Quantum Inc. (NASDAQ: QBTS), thanks to major investor enthusiasm around the growing commercial adoption of the technology. However, a more dominant theme for the year may be D-Wave's seemingly perpetual decline, which has ultimately led to shares falling about 40% since Jan. 1.
Late summer has brought renewed skepticism as investors reassess D-Wave's financial performance and how the firm compares to other quantum names in a highly competitive environment.
