Shares of several quantum computing companies soared on Thursday, extending gains from the previous day despite a broader market downturn.
The rally was led by D-Wave Quantum (NYSE:QBTS), which saw its stock climb 15% to $6.71 after forecasting quarterly revenue that exceeded analysts’ expectations.
The company’s shares had already risen 8% on Wednesday following the publication of a peer-reviewed paper in Science, claiming its quantum computer outperformed a top-tier classical supercomputer.
Quantum computers, leveraging the principles of quantum mechanics, offer superior speed and efficiency over traditional systems, excelling in parallel processing, multi-path predictions, and vast data storage.
The sector’s momentum lifted other players as well.
Quantum Corp (NASDAQ:QMCO) surged 26%, poised for its largest daily gain since mid-February, after a 10% increase on Wednesday.
Quantum Computing (NASDAQ:QUBT) edged up 2%, defying a sharp decline in the broader market, with the Nasdaq Composite dropping over 2% in afternoon trading.
However, not all quantum stocks followed the upward trend.
IonQ (NYSE:IONQ) fell 5.3% to $20.68 after Kerrisdale Capital announced a short position in the stock.
IonQ has struggled in 2025, down roughly 50% year-to-date, though it soared more than 200% in 2024.
