3 Best Quantum Computing Stocks to Buy in April 2026, According to Analysts

Quantum computing is entering a new phase in 2026, as real technical breakthroughs, government contracts, and early commercial deployments replace years of mostly theoretical progress. Further, Nvidia’s (NVDA) new quantum‑AI Ising models have also helped boost sector momentum, pushing investors to revisit pure‑play quantum names. April 2026 seems to be a good time to buy, as valuations have reset after a volatile year and recent breakthroughs suggest the long-awaited quantum growth cycle may finally be starting.

Here are today’s top quantum computing stock picks. Click on any ticker to thoroughly research the stock before you decide whether to add it to your portfolio.

1. Rigetti (RGTI): Rigetti recently launched its 108‑qubit Cepheus‑1‑108Q system, the largest modular multi-chip quantum computer in the industry. The new system triples the company’s previous qubit count and delivers 99.1% median two‑qubit gate fidelity, with a goal of reaching 99.5% later this year.
   Also, Rigetti’s planned $100 million UK expansion toward a 1,000‑qubit system and recent hardware sales, including a Novera QPU to the University of Saskatchewan, reflect its growing commercial traction.
   Currently, RGTI stock has an analyst consensus of Strong Buy. With an average price target of $32.33, the stock has an implied upside potential of 66.32%.
   
2. IonQ (IONQ): The company delivered the first-ever photonic link between two trapped-ion systems, effectively the world’s first connected commercial quantum computers, in 2026. IonQ also won a major DARPA HARQ contract to develop high‑speed quantum interconnects for defense use.
   Importantly, these advances are built on strong fundamentals. IonQ is the first public quantum company to surpass $100 million in annual GAAP revenue.
   IONQ stock has an analyst consensus of Strong Buy, with an average price target of $65.91, suggesting an upside of 47.95%.
   
3. D-Wave Quantum (QBTS): D‑Wave continues to stand out with its dual‑platform strategy, strengthened by its acquisition of Quantum Circuits, which makes it the only quantum company offering both annealing and gate‑model systems.
   The company reported strong bookings, growing government and enterprise use cases, and steady progress on its Advantage2 and gate‑model roadmaps.
   QBTS stock has an analyst consensus of Strong Buy and carries an average price target of $38.18, indicating a 78.41% upside potential.
