qbts vs qubt vs ionq vs rgti which quantum computing stocks retail

The recent market sell-off led by artificial intelligence (AI) names did not spare quantum computing stocks, with most pulling back after peaking in early to mid-October. The Defiance Quantum ETF (QTUM), which is currently up 35% year-to-date (YTD), traded with gains of over 41% in early November. With the quantum computing stocks as a group trading off their peaks, we asked Stocktwits users, “Are you buying the dip” on a list of stocks, including D-Wave (QBTS), Rigetti (RGTI), Quantum Computing (QUBT)... The results of the poll, which received responses from nearly 8,000 Stocktwits users, showed that a majority (35%) looked to buy the dip in IonQ stock. Rigetti was mentioned by 28% of the users, D-Wave by 23% and Quantum Computing by a more modest 14% users. The responses posted on the polls timeline, though, showed general trader pessimism about these stocks despite their recent dip.

One user said these stocks are still overvalued. Another user said these SMID-cap quantum names are significantly behind those of IBM (IBM) and Alphabet (GOOGL). The user viewed these big tech companies as clear leaders. The quantum computing space has been heating up rapidly, but we’re still in the early stages. This means IonQ (NYSE:IONQ), Rigetti Computing (NASDAQ:RGTI), and D-Wave Quantum (NYSE:QBTS) have all been lifted by the rising tide. But if that tide continues rising, or once commercially viable quantum computing (or QC) becomes a reality, not every QC startup has the buoyancy to rise all the way to the top.

Almost every quantum computing startup has its own way of trying to make QC commercially viable. There will only be a handful of direct QC winners. And it is debatable whether or not the biggest winner will be from the current batch of QC companies that are publicly tradable. OpenAI was the first AI company to achieve a breakthrough, despite public companies having their own AI teams with deeper pockets. With that in mind, it requires careful consideration before you pick between the popular quantum computing stocks in the market right now. If you’re in it for the long run, it’s even more important to research them individually and determine which one will ultimately prevail.

Let’s take a look. IonQ has historically led the quantum computing startup space, and it does have very impressive tech. It has the lowest error rates in the QC business, with 99.99% fidelity on two-qubit gates. As of today, it has Forte, with 36 physical qubits. It already has customers. Namely, Airbus (OTCMKTS:EADSY), Hyundai, and the U.S.

In the most recent regular session (Friday), several of the best-known “pure-play” quantum names posted sharp declines even as the broader U.S. market largely drifted in quiet, post-holiday trade. IonQ (IONQ) finished at $46.00, down about 7.6%. Rigetti Computing (RGTI) closed at $22.38, down roughly 8.6%. D-Wave Quantum (QBTS) ended at $25.29, down about 8.1%. Quantum Computing Inc.

(QUBT) closed at $10.66, down around 6.5%. That kind of synchronized pullback is not unusual for the sector: quantum “pure plays” often trade like a single high-beta theme—moving together on sentiment, valuation, and market microstructure—especially when volumes are lighter than normal. Friday’s session came in the heart of the year-end “Santa Claus rally” window, when trading volumes often thin out and day-to-day moves can become exaggerated, particularly in smaller, story-driven stocks. A Comparison of QUBT, QBTS, IONQ, and RGTI Quantum computing is an exciting frontier in technology, with several key players pioneering unique approaches to harnessing the power of quantum systems. In this article, we compare four major companies: Quantum Computing Inc.

(QUBT), D-Wave Quantum Inc. (QBTS), IonQ Inc. (IONQ), and Rigetti Computing Inc. (RGTI). Each company employs distinct technologies and strategies, shaping their strengths and market potential. QUBT focuses on developing quantum software and applications that make quantum computing accessible to users without requiring deep quantum expertise.

Their user-friendly platforms bridge classical and quantum systems, enabling seamless integration into existing workflows. QBTS specializes in quantum annealing, a method particularly effective for solving optimization problems such as logistics and scheduling. While quantum annealing excels in specific applications, it differs from the universal gate-based quantum computing pursued by other companies. IONQ uses trapped-ion technology for its quantum computers, providing advantages in qubit quality and scalability. Their systems are available through cloud platforms, allowing researchers and businesses to experiment with quantum algorithms. IonQ’s strong revenue growth highlights its increasing commercial traction.

Just two weeks ago (here), I laid out a tactical plan for trading the emerging leaders in the quantum space. Since then, IonQ (IONQ), Rigetti Computing (RGTI), and D-Wave Quantum (QBTS) have delivered explosive rallies, rewarding traders who were positioned and pushing the group further into the spotlight. What was once considered a distant, almost science fiction theme is now moving rapidly toward commercialization, with major breakthroughs, expanding government support, and institutional investors beginning to take notice. While the quantum computing sector has exploded over the past year, the industry remains tiny compared to the broader market and its long-term potential. So even if sentiment feels frothy at times, quantum is still a relatively small space with plenty of room to grow. In this piece, we’ll break down the latest company developments, put the sector’s scope and market value in perspective, and examine the technical setups that could determine whether this rally has more legs, or...

Since my last piece, each of the leading quantum stocks has delivered fresh developments that highlight both the growth and the speculative nature of the sector. IonQ completed its acquisition of Oxford Ionics, a UK-based quantum startup, strengthening its technological roadmap and expanding its international footprint. The deal reinforces IonQ’s strategy of building a diversified quantum portfolio, from computing to networking to sensing. QUBT Quick QuoteQUBT IONQ Quick QuoteIONQ QBTS Quick QuoteQBTS Quantum computing remains one of the hottest and most speculative corners of the market, delivering eye-popping returns over the past year, and even greater upside potential as the technology moves closer to real-world applications. While the technology is still in its early stages, recent advancements have sparked an accelerating interest in the sector, with capital flowing into the handful of public companies operating at the frontier.

Over the past year, D-WAVE QUANTUM ((QBTS Quick QuoteQBTS - Free Report) ) has emerged as a standout, and just this week the stock broke out from a technical pattern on rising volume. Other leading names in the sector such as Quantum Computing Inc. ((QUBT Quick QuoteQUBT - Free Report) ) and IonQ ((IONQ Quick QuoteIONQ - Free Report) ) appear to be on the verge of a breakout as well, with both stocks forming compelling technical setups. All three stocks remain highly volatile, relatively early-stage plays, but they also offer enormous upside in a market hungry for innovation. Below, I break down the technical setups, key levels, and momentum signals to watch in each name. D-Wave Quantum is a pioneering player in the quantum computing space, focused on commercializing quantum annealing technology.

While its approach differs from the gate-based quantum systems used by rivals, D-Wave has made significant progress in delivering practical quantum solutions for optimization problems across logistics, manufacturing, and artificial intelligence. Governments and private investors are investing heavily in quantum computing. This is pushing the technology toward real-world applications. Experts predict the market will hit about $4.24 billion by 2030. It is expected to grow roughly 20.5% each year from 2025 to 2030. Artificial intelligence has changed investing.

When paired with quantum computing, it may create big wealth-building chances in the coming decades. <img fetchpriority="high" decoding="async" class="aligncenter wp-image-37762" src="https://carboncredits.com/wp-content/uploads/2025/10/Screenshot_3-10-2025_11744_www.grandviewresearch.com_-300x172.jpeg" alt="quantum stocks quantum computing" width="650" height="372" srcset="https://carboncredits.com/wp-content/uploads/2025/10/Screenshot_3-10-2025_11744_www.grandviewresearch.com_-300x172.jpeg 300w, https://carboncredits.com/wp-content/uploads/2025/10/Screenshot_3-10-2025_11744_www.grandviewresearch.com_-1024x586.jpeg 1024w, https://carboncredits.com/wp-content/uploads/2025/10/Screenshot_3-10-2025_11744_www.grandviewresearch.com_-768x440.jpeg 768w, https://carboncredits.com/wp-content/uploads/2025/10/Screenshot_3-10-2025_11744_www.grandviewresearch.com_-696x398.jpeg 696w, https://carboncredits.com/wp-content/uploads/2025/10/Screenshot_3-10-2025_11744_www.grandviewresearch.com_.jpeg 1064w" sizes="(max-width: 650px) 100vw, 650px" /> Recent breakthroughs in qubit stability and new partnerships for larger quantum networks are driving growth. Leading pure-play quantum stocks have risen as investors bet on widespread commercial use. These companies are at the forefront, turning advanced research into real solutions. They could reshape industries like pharmaceuticals and energy.

Quantum computing has long promised a leap in processing power beyond classical limits. The spotlight on this niche sector has intensified recently, with NVIDIA’s NVDA CEO Jensen Huang declaring that quantum computing is reaching an “inflection point,” a sharp shift from his earlier stance that practical use... Meanwhile, International Business Machines IBM unveiled an ambitious roadmap targeting a large-scale, fault-tolerant quantum computer (codenamed Starling) by 2029. Against this backdrop, investors are increasingly exploring pure-play opportunities in the sector. Three publicly listed quantum firms, IonQ IONQ, D-Wave Quantum QBTS and Rigetti Computing RGTI, have emerged with their distinct strategies and progress. Their last-reported first-quarter 2025 earnings reveal how each is advancing on technology, revenues and financial stability.

One of IonQ’s recent milestones is the $22 million sale of 50% compute capacity from its Forte Enterprise system to EPB Chattanooga, marking the industry’s first commercial deployment that combines a quantum network and... IonQ announced a series of strategic acquisitions to strengthen its technological edge — the $1.1 billion acquisition of Oxford Ionics (noted outside the earnings call) and the planned purchases of Lightsynq and Capella, which... The company also signed MOUs with Toyota Tsusho, Japan’s AIST (G-QuAT division), and satellite tech firm Intellian to explore quantum key distribution in space. IonQ was also selected to participate in DARPA’s Quantum Benchmarking Initiative, further validating its leadership in advancing measurable quantum performance. This Zacks Rank #2 (Buy) stock is currently trading 27.6% below its 52-week high of $54.74, which offers a potential upside for new buyers. The Zacks Consensus Estimate for IonQ’s 2025 earnings implies a 69.9% improvement over 2024.
