The quantum computing sector has exhibited significant volatility, particularly in April 2026, amid changing macroeconomic conditions and shifting investor sentiment after a prior surge in 2024-2025. Many publicly traded quantum firms remain unprofitable, leading to fluctuating valuations highly sensitive to liquidity and interest rates. Despite these challenges, McKinsey forecasts that the quantum market could reach $100 billion in ten years, although growth is expected to be uneven.
NVIDIA’s Impact on Quantum-AI Collaboration
A pivotal trend is the convergence of quantum computing with artificial intelligence, highlighted by NVIDIA’s introduction of Ising quantum-AI models on April 14, 2026, which focus on error correction. This development has sparked renewed investor interest, with stocks like IonQ (IONQ) and Rigetti Computing (RGTI) experiencing double-digit gains. For 2026, IonQ is projected to achieve a 46.2% increase in earnings and 82.2% growth in revenue, while Rigetti expects earnings growth of 73.4% and high revenue growth of 254.7%.
Stock Performance and Projections
Current price targets for IonQ suggest a potential 42% increase, and for Rigetti, a 62% increase from their latest market values. Both companies are strengthening their partnerships with NVIDIA, aligning with trends in hybrid quantum-classical computing architectures, which are viewed as key to commercialization in the near term.
