Deep Value Deep Tech: 10 Quantum Computing Stocks Investors Accidentally Dumped

Page 1 of 3

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. While we think the stock presents a compelling opportunity after the price dip, you could also look at what insiders are buying if you think that’s a stronger signal of buying quality stocks at discounted prices: Buy the Dip: 10 Stocks Insiders Are Loading Up On After the Recent Market Sell-Off.
