ionq vs d wave which quantum computing stock will outperform in 2026

Written by Manali Pradhan for The Motley Fool-> IonQ’s rapidly scaling revenue base and contracted backlog are solid positives for the company. D-Wave Quantum’s quantum annealing technology has demonstrated applicability in real-world use cases. Both stocks are trading at extremely rich valuations. Quantum computing is advancing gradually from academic pursuit to early commercialization, and according to the market research firm The Quantum Insider, between now and 2035, the technology could add more than $1 trillion to... Two leading quantum computing companies posted improved financial results in the first quarter of 2025.

Both D-Wave Quantum and IonQ showed progress in their distinct approaches to quantum technology development. D-Wave launched its production-ready Advantage2 quantum system in May 2025. The sixth-generation quantum annealer features over 4,400 qubits with 40% greater energy scale than previous versions. The system also delivers 75% noise reduction and double the coherence of earlier models. D-Wave targets practical business applications like optimization and artificial intelligence with its quantum annealing approach. IonQ takes a different path with gate-based quantum systems designed for complex problems.

The company completed three strategic acquisitions to build a vertically integrated platform. These purchases included Lightsynq for photonic interconnects, Capella Space for satellite quantum key distribution, and Oxford Ionics for ion-trap research. IonQ aims to create scalable systems with millions of qubits for future quantum internet applications. D-Wave is taking a dual approach to quantum computing led by its annealing technology. IonQ is using a trapped-ion gate-based system. Both stocks remain speculative at this point.

Two of the leading pure-play quantum computing stocks are IonQ (NYSE: IONQ) and D-Wave Quantum (NYSE: QBTS). While both stocks have enjoyed solid returns thus far this year, D-Wave has been the much stronger performer, with the stock up around 200% as of this writing versus only a 10% gain for... Let's examine which stock is set up to outperform in 2026. As 2026 approaches, D-Wave Quantum Inc. (QBTS - Free Report) and IonQ (IONQ - Free Report) present distinct investment narratives in the burgeoning quantum computing sector. In 2025, D-Wave’s official disclosures show strong commercial momentum, including robust third-quarter results with revenue and gross profit more than doubling year-over-year and cash balances hitting record highs, alongside product and business expansions such...

government-focused business units. IonQ, on the other hand, reported gains through strategic partnerships and deployments, such as finalizing delivery of its 100-qubit Tempo system to South Korea’s KISTI and expanding long-term collaborations in Europe, reinforcing global market... D-Wave stock has surged 227.6% year-to-date, far outpacing IonQ’s 19.2% gain, the broader Internet-Software industry’s 10.4% rise, the Computer and Technology sector’s 27.7% rally, and the S&P 500’s 20% increase, reflecting divergent investor sentiment... Let’s find out how things are shaping up for 2026. Two of the leading pure-play quantum computing stocks are IonQ (NYSE: IONQ) and D-Wave Quantum (NYSE: QBTS). While both stocks have enjoyed solid returns thus far this year, D-Wave has been the much stronger performer, with the stock up around 200% as of this writing versus only a 10% gain for...

Let's examine which stock is set up to outperform in 2026. While most quantum computing companies use what is known as gate-based systems, D-Wave has taken a different approach and employs quantum annealing technology. Annealing is a more specialized process used to find the best way to do something. In many ways, the difference between the technologies is similar to what we are seeing in artificial intelligence (AI) today. Gate-based systems are like general-purpose graphics processing units (GPUs) that can do many things well, while annealing is more like ASICs, which are designed to optimally perform very specific tasks. © All rights reserved.
