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.
