2026 has been a special year for Quantum Computing, not just because of the technological developments and stock performance, but also because it is the year that has given us more quantum pure-plays in the form of fresh IPOs. Quantum Computing is one of those areas where the stock market keeps bouncing between severe pessimism and extreme optimism. The last week or so has given us the worst of these stocks, but none of the selling pressure was induced by company-specific news.
As a result, investors who dumped stocks in every sector helped provide attractive entry points for quantum computing stocks. This is what gave me the motivation to write on the 10 quantum computing stocks investors accidentally dumped.
Quantum computing stocks rallied in the middle of the year only to fall back sharply by the beginning of August. That’s when Gary Mobley, an analyst at Benchmark, pointed out the opportunity that this industry presents:
“We are bullish on the quantum computing sector. We see the legitimacy of the technology further building on the recent momentum. In quantum computing, it is not a ‘winner-takes-all’ situation. In these still early days of quantum computing, and prior to the broad achievement of QA, the best strategy for investors may be to take a portfolio approach to investing in the sector.”
When the market declined early last week because of the US election results, quantum stocks went down too, to the same level they were at when Mobley made the above comments. It is therefore worth revisiting his theses on these companies in order to capitalize on the opportunity. These companies are doing better than their stock’s price action suggests and are therefore worth a deeper look.

Methodology
To come up with my list of 10 Quantum Computing Stocks Investors Accidentally Dumped, I looked at companies that derive a major portion of their revenue from quantum computing and are therefore pure-plays. These stocks were caught in the sell-off post Nov 3 mid-term elections and, with no change in the fundamentals of quantum computing, were dumped by investors purely due to the market-wide sell-off. I included companies with a market cap of at least $500 million to include companies that were listed this year and are still early in their growth phase. I then looked at the potential upside of these stocks according to the median analyst price target and ranked them in ascending order of their potential upside.
10. IonQ Inc. (NYSE:IONQ)
Potential Upside: 42.9%
Despite posting the strongest quarter in its history, IonQ Inc. (NYSE:IONQ) has faced selling pressure alongside its quantum peers. Wedbush Securities reported declines of 25% to 40% across the group since late September. The firm reaffirmed an Outperform rating on the IonQ stock while describing the company as the scale leader. But it trimmed its price target from $75 to $50.
IonQ reported third-quarter revenue of $173.8 million, marking a 336% increase and comfortably beating the consensus estimate of $141.2 million. The company’s quantum platform accounted for approximately $90 million, compared with about $84 million from the chip-making unit. It also raised its 2026 revenue outlook to $505 million to $515 million, up from its previous forecast of $450 million to $460 million. IonQ has already sold out its 256-qubit capacity for 2027 and has $1.2 billion in contracted backlog.
The firm also has substantial financial resources to support its expansions. It raised $2 billion in October at a premium to its stock price, bringing pro forma cash balance to $3.7 billion. Moreover, IonQ is the only trapped-ion company in the final stage of a DARPA quantum program that could be worth up to $300 million.

9. Quantinuum Inc. (NASDAQ:QNT)
Potential Upside: 51.16%
Quantinuum Inc. (NASDAQ:QNT) has lost roughly 45% since pricing its IPO at $60 in June. However, its business performance has been stronger than the stock’s performance. In the third quarter, revenue climbed 233% to $9.1 million, surpassing analyst estimates of approximately $8 million. The adjusted loss narrowed to $0.29 per share, better than the expected $0.37. The company also lifted its 2026 revenue guidance to $31 million to $34 million from its previous range of $28 million to $32 million.
Quantinuum’s technology remains its biggest strength. Its Helios system achieved 99.9995% accuracy in error correction, setting a world record with just five errors per million operations. This is a tenfold improvement over its previous record set a month earlier and 100 times better than the best published result from other hardware types. Wedbush Securities called the development a high-signal milestone. The firm believes roughly one error per million operations may be needed for the first truly useful error-corrected applications.
Quantinuum is gaining support from its key partners as well. Japan’s RIKEN research institute has broadened its collaboration with the company to develop quantum-AI hybrid computing systems and a fault-tolerant quantum computer using Japanese-made components.

8. IQM Quantum Computers Oyj (NASDAQ:IQMX)
Potential Upside: 60.87%
Although IQM Quantum Computers Oyj (NASDAQ:IQMX) only recently entered the public markets, its shares have already faced heavy selling pressure. The Finnish company listed on Nasdaq and Nasdaq Helsinki in July 2026. On November 9, the stock closed at $8.31, down about 45% from its 52-week high of $15.10. Shares have also slipped below the previous low reached in late October. The selloff has made IQM Quantum one of the cheaper ways to gain exposure to a quantum hardware company that is already generating sales. It has sold 31 quantum computers to date. The company’s order backlog stands at €102.5 million, representing more than twice its full-year revenue guidance. At the end of September, IQM held €260.4 million in cash. That cash balance represents roughly 20% of its $1.57 billion market cap. Here are 10 more stocks that are cash rich and offer a better valuation than IQMX: 10 Activist Target Stocks with High Cash and Low Valuation.
The company develops full-stack superconducting quantum computers and sells complete systems to supercomputing centers, businesses, and universities. This gives it a more direct revenue source than many of its peers. In the third quarter, revenue rose 51% year over year to €8.9 million, while gross margin reached 47%. IQM secured €42.2 million in new orders during the quarter, pushing its backlog 52% higher since the start of the year.
7. Horizon Quantum Holdings Ltd. (NASDAQ:HQ)
Potential Upside: 62.83%
Horizon Quantum Holdings Ltd. (NASDAQ:HQ) has seen some of the sharpest price swings among quantum stocks in 2026. The Singapore-based software company entered the public market in March 2026 through its SPAC merger with dMY Squared. Its shares reached an all-time high of $45 before falling to $13.81 by November 9, leaving them about 69% below that peak. The volatility has also triggered extreme trading sessions. The stock dropped 32% on September 14 alone and has faced multiple trading halts due to volatility.
However, its financial position offers a different picture. Horizon Quantum ended June with $113.3 million in cash and spent only $5.1 million on operating activities in the second quarter. At that rate, its cash balance could support operations for several years. Here are other stocks that offer high growth: 10 Best High Growth Stocks Outside Big Tech.
The company develops the software layer that allows developers to write quantum programs once and run them across different types of quantum hardware. It opened early access to Beryllium, which is an object-oriented quantum programming language, near the end of the second quarter. Horizon Quantum’s Ember-1 testbed in Singapore, which uses a Rigetti chip, is also running real-time programs with features such as loops and recursion. In November, the company announced a planned $27 million acquisition of Entropica Labs and added OQC’s 32-qubit processor to its Triple Alpha development environment.
6. Rigetti Computing Inc. (NASDAQ:RGTI)
Potential Upside: 105.76%
Rigetti Computing Inc. (NASDAQ:RGTI) has lost about 45% of its value this year. Wedbush Securities says the broader quantum group has also declined 25% to 40% since late September. Despite the decline, the firm maintains an Outperform rating on the stock. However, Wedbush Analyst Matt Bryson lowered his price target on the stock from $37 to $25. The updated price target implies more than 100% upside from the current share price.
Despite the weakness in its share price, Rigetti Computing’s underlying business has made progress on both technical and financial fronts. The median accuracy of two-qubit operations on its flagship chip has reached 99.5%, compared with about 99.1% in the previous quarter. This progress matters because lower errors help the company to build larger machines that can function reliably. Gross margin improved sharply from 21% a year ago to approximately 61% in the latest quarter. Meanwhile, revenue for the first nine months more than doubled to $10.9 million. For the full year, management projects revenue to reach around $20 million.
Rigetti also has strong financial and government backing. The company has finalized a $100 million research funding deal with the U.S. Department of Commerce, which will receive a small ownership stake in return. It ended the quarter with $497.1 million in cash and cash equivalents and no debt. Management’s next target is a system featuring more than 300 qubits and around 99.7% accuracy by mid-2028. Rigetti continues to deliver impressive technological advancements but is still in an early stage compares to many stocks in our 10 Best Tech Stocks That Pay Dividends list.
5. Infleqtion Inc. (NYSE:INFQ)
Potential Upside: 113.9%
Infleqtion Inc. (NYSE:INFQ) is another quantum stock where the share price has moved in the opposite direction from business progress. The neutral-atom quantum company went public in February 2026, and since then it has reached several important technology milestones. But the stock closed at $9.66 on November 9, after losing about 55% of its value from the 52-week high of $21.28. It was also 32.5% below its August 27 closing price of $14.32. Over the last 20 trading sessions, shares fell as low as $7.01. Meanwhile, second-quarter revenue rose 157% year over year, and the company achieved its 2026 logical-qubit target ahead of its third-quarter report. The selloff has left investors with exposure to a growing quantum company at less than half its previous peak price.

Infleqtion has a more diversified revenue base than many companies focused purely on quantum computing. It also supplies quantum sensors, RF receivers, and atomic clocks, primarily to government agencies. These products generate revenue while its quantum computing business continues to develop. In the second quarter, the company generated $13.5 million in revenue, bringing its trailing twelve-month revenue to around $42 million.
4. Quantum Computing Inc. (NASDAQ:QUBT)
Potential Upside: 217.46%
Since late September, quantum stocks have faced heavy selling pressure. Wedbush Securities says the group, including Quantum Computing Inc. (NASDAQ:QUBT), has fallen around 25% to 40%. The firm attributes the weakness to share sales and the fact that much of the revenue arrives later in the year. However, it remains confident in the technology. This suggests the decline is driven by investor sentiment rather than problems with the underlying businesses.
Quantum Computing reflects the same pattern. The company reported record third-quarter revenue of $9.5 million, compared with $384,000 a year earlier. It also exceeded analyst expectations of $7.6 million. Most of the revenue came from photonics businesses acquired earlier this year. Beyond revenue, Quantum Computing has built a backlog of $39.1 million. Its new Dirac-3S machine is also expected to ship to its first customer this quarter. A deal with INmune Bio has also brought in the company’s first customer from the drug industry.
The biggest attraction is the gap between Quantum Computing’s cash position and its market value. The company has about $1.3 billion in cash and investments, compared with a market value of roughly $1.55 billion. That leaves investors paying relatively little for the underlying technology. However, if you prefer to buy stocks that have a lot going for them today instead of some future date, you can look at our 10 Stocks to Watch from Morgan Stanley’s Ultra-Selective Tailwinds Strategy.
3. D-Wave Quantum Inc. (NASDAQ:QBTS)
Potential Upside: 233.97%
D-Wave Quantum Inc. (NASDAQ:QBTS) shares dropped roughly 45% between the company’s August report and early November, despite continued progress in the business. Wedbush Securities has maintained its Outperform rating. However, the firm cut its price target from $37 to $30. The updated price target is still more than double the current share price. It also considers D-Wave one of the most attractive upside opportunities among the quantum companies it follows.
Analysts have been slashing price targets across the board for various reasons, some of which might be unwarranted: Analysts Just Slashed Their Price Targets on These 10 Stocks.
New customer commitments are supporting the company’s growth. First-half bookings, which included a system for Florida Atlantic University, rose to $35.5 million. Its backlog now sits at around $40.7 million. It has also delivered its 4,400-plus qubit Advantage2 computer to Italy. Swiss Quantum Technology backed the deal with a €10 million commitment for half the computer’s capacity over five years. D-Wave also extended its multi-year chip-making partnership with SkyWater after a joint test reduced factory delays by up to 30%.
Moreover, the company is advancing beyond its core business. Its gate-model simulator beta allows BBVA, Florida Atlantic University, and the Jülich Supercomputing Center to evaluate its error-correction approach early. Management expects most of this year’s revenue in the fourth quarter, when it plans to deliver two annealing systems.
2. Pasqal Holding SA(NASDAQ:PSQL)
Potential Upside: 236.32%
Despite starting with a strong rally, Pasqal Holding SA(NASDAQ:PSQL) experienced a sharp selloff shortly after going public. The company completed its SPAC merger with Bleichroeder Acquisition Corp. II on August 27, 2026. Just four days later, shares reached an intraday high of $24.69 before losing 54% over the next four trading sessions. By November 11, the stock had fallen to $4.46, down more than 80% from its all-time high and around 56% from its first-day closing price of $9.79.
However, Pasqal has made rapid progress in both its technology and commercial operations. On the technology side, the company successfully trapped 1,024 defect-free atoms, doubling its previous record. A new cryogenic design has also increased atom lifetimes by around 40 times. Meanwhile, trapping atoms on a photonic integrated circuit chip could allow Pasqal to reduce the optics required in its machines by up to 50 times.
These improvements are beginning to translate into commercial deployments. The company launched a 200-qubit system in Saudi Arabia with Aramco, integrated a 140-qubit processor with Italy’s Leonardo supercomputer. Its systems are also available through Google Cloud and Microsoft Azure.

1. Xanadu Quantum Technologies Limited (NASDAQ:XNDU)
Potential Upside: 691.37%
Xanadu Quantum Technologies Limited (NASDAQ:XNDU) has suffered the steepest decline among all the stocks on this list. The company went public in March 2026 through a merger with SPAC Crane Harbor Acquisition Corp. Its shares peaked at $42.44 but dropped to $2.80 on November 11, representing a loss of about 93%. Several events drove the decline. In May, shares dropped roughly 68% in premarket trading after Xanadu Quantum filed to register up to 293.66 million shares for resale by existing holders. The stock faced another wave of selling in September, when it fell around 56% during the month. This included a 21.6% decline on September 22, as the six-month lockup period expired. Notably, much of this selling pressure came from the availability of additional shares rather than weakness in the underlying business. That gap between the stock’s performance and its business prospects is one reason Wall Street sees the highest upside potential in Xanadu Quantum among the stocks on this list. Here are 10 more stocks that have a similar potential for the next 12 months: 10 Stocks That Could Skyrocket in 2027.
XNDU’s computers rely on photons, or particles of light, rather than other types of qubits. The company believes its technology could be easier to scale than competing approaches because photonic chips can be manufactured in conventional semiconductor fabs. Its October agreement with GlobalFoundries established a multi-year manufacturing partnership, while its work with ASML focuses on lithography processes for photonic hardware.
