New quantum startup Infleqtion uses atoms for its quantum components, just like IonQ.
Infleqtion's quantum computing accuracy is much lower than best-in-class IonQ.
Infleqtion's additional business lines and lower price could help it outperform IonQ this year.
Given the wild success that quantum computing start-ups like IonQ (NYSE: IONQ) enjoyed in 2025, it's no surprise that even more new players have entered the field in 2026.
One of these contenders for quantum dominance is Infleqtion (NYSE: INFQ), which briefly reached a market cap of $6 billion in April, despite going public only in February.

But could this scrappy upstart's performance really crush the more established IonQ in 2026? I believe it could. Here's how Infleqtion might pull it off.
While other quantum computing companies use subatomic particles like electrons or photons, both Infleqtion and IonQ use entire atoms instead. The benefit, according to both companies, is that for certain elemental types, all atoms of the same type in the universe are identical. This reduces manufacturing costs and the potential for defects.
IonQ utilizes ionized ytterbium atoms in its quantum components, while Infleqtion uses neutral rubidium and cesium atoms. But the big difference between the companies' quantum computers is their accuracy.
Accuracy in quantum computing is measured by "two-qubit gate fidelity." In October, IonQ became the first quantum computing company to achieve two-qubit gate fidelity of 99.99%. That's highly accurate, but considering classical computers essentially have 100% accuracy, it's still less than ideal.
Infleqtion, on the other hand, claims two-qubit gate fidelity of only 99.73%, which is a world away in computing terms. So how could Infleqtion possibly outperform IonQ?
Luckily for Infleqtion, it doesn't necessarily need to close the quantum computing accuracy gap for its stock to outperform IonQ's this year.
Infleqtion uses quantum technology for more than just computing. The company is a pioneer in quantum sensing technology, manufacturing devices that utilize neutral-atom technology for precise measurements. Its Tiqker atomic clock is more precise than a standard microwave atomic clock, while its quantum inertial sensors can utilize gravitational fields to provide precise positioning information in the absence of GPS and in outer space. Infleqtion already counts U.S. government entities NASA and the U.S. Navy among its clients, so this could be a major growth area independent of its quantum computing business.
But the big reason Infleqtion might outperform IonQ this year is simple volatility.
Even though IonQ's market cap is more than six times as large as Infleqtion's, both stocks have been subject to wild price swings. Over the past year, IonQ's market cap has ranged from $8 billion to $27.2 billion, while Infleqtion's has ranged between $1.9 billion and $3.8 billion since its February IPO.
Right now, however, Infleqtion is trading at a $2.7 billion valuation, close to its average of $2.6 billion. IonQ, on the other hand, is currently trading at $19.4 billion, well above its $15.2 billion one-year average.
All it might take is a bit of good news from the much smaller Infleqtion to cause its stock to soar and outperform IonQ's in 2026. But the opposite is also true: A bit of bad news is all it might take to send Infleqtion's shares tumbling. Investors should be aware of the volatility of both companies, and only the most risk-tolerant investors should consider buying either quantum computing stock.

Four leading AI models discuss this article
"Infleqtion's lower fidelity is a fundamental technical disadvantage that cannot be offset by mere stock price volatility or secondary business lines in the short term."
The article conflates stock price volatility with fundamental business viability, which is a dangerous trap for retail investors. While Infleqtion’s diversification into quantum sensing—specifically GPS-denied navigation for defense—offers a tangible revenue stream that IonQ currently lacks, the valuation gap is based on speculative 'what-ifs' rather than operational milestones. IonQ’s 99.99% gate fidelity is a massive competitive moat; in quantum, the difference between 99.73% and 99.99% is not linear—it is exponential in terms of error correction requirements. Betting on Infleqtion because it is 'cheaper' ignores the high burn rate inherent in scaling neutral-atom hardware. Investors are essentially choosing between a premium, high-fidelity platform and a diversified, lower-fidelity hardware play.
If Infleqtion’s sensing business achieves rapid adoption within the defense sector, it could provide the non-dilutive capital needed to iterate their quantum hardware faster than IonQ, effectively subsidizing their R&D through government contracts.

"Infleqtion's stock outperformance thesis rests on volatility arbitrage and diversification, not technical superiority—but IonQ's accuracy gap is a moat that matters more than revenue mix in a space where error rates determine viability."
This article conflates stock price volatility with investment merit—a dangerous trap. Yes, Infleqtion is smaller and thus more volatile, but that's a feature of illiquidity, not a reason to expect outperformance. The article acknowledges IonQ's 99.99% two-qubit fidelity versus Infleqtion's 99.73%—a gap that compounds catastrophically in quantum systems. Infleqtion's sensing business (Tiqker clocks, inertial sensors) is real but niche; government contracts don't scale like enterprise quantum computing. The article's core thesis—that volatility + diversified revenue = stock crush—ignores that IonQ is trading at 1.28x its one-year average while Infleqtion sits near its mean. Small-cap volatility cuts both ways.
If Infleqtion's sensing business generates recurring, high-margin government revenue while quantum computing remains speculative for both firms, the diversification could genuinely reduce downside risk and support a valuation multiple that outperforms a single-product IonQ over 12-24 months.
"Infleqtion faces a meaningful hurdle from a 0.26 percentage point fidelity gap and uncertain near-term compute traction, making 2026 outperformance unlikely absent a transformative breakthrough."
Infleqtion trades on volatility and non-core lines, but the core math argues against a 2026 outperformance versus IonQ. Infleqtion claims 99.73% two-qubit fidelity vs IonQ's 99.99%—a meaningful gap given quantum compute scaling—and its government sensing business may help revenue, but it doesn't replace compute capability. With INFQ around $2.7B vs IONQ near $19B, a sentiment flip or a large government win would be required to justify multiple expansion. Absent a clear path to closing the fidelity gap or a deployable software ecosystem, upside hinges on luck, not fundamentals.
The sensing business and optionality on government contracts could catalyze rapid upside; even a small win could unlock outsized relief in sentiment and valuation.
"Government-backed quantum sensing provides a critical, non-dilutive capital advantage that compensates for Infleqtion's current fidelity deficit."
Claude, you dismiss government contracts as 'niche,' but that ignores the strategic 'dual-use' reality. In the current geopolitical climate, quantum sensing for GPS-denied navigation is a national security priority, not a niche hobby. This provides Infleqtion with a non-dilutive R&D subsidy that IonQ lacks. While IonQ leads in pure compute fidelity, Infleqtion is building a moat in hardware durability. The real risk isn't fidelity; it's whether Infleqtion can bridge the gap between lab-grade sensing and scalable manufacturing.

"Government contracts provide runway, not competitive parity in quantum compute fidelity."
Gemini conflates government funding with competitive advantage. Yes, defense contracts provide non-dilutive capital—that's real. But it doesn't close the fidelity gap, which compounds exponentially in error correction. A $500M sensing contract doesn't fix 99.73% vs 99.99%. The dual-use argument assumes Infleqtion can simultaneously scale sensing *and* catch up in compute. Manufacturing durability is table-stakes, not a moat. The real question: does sensing revenue actually fund quantum R&D faster than IonQ's cash burn, or does it just delay the reckoning?
"The real gating factors are policy/timing, manufacturability, and ecosystem, not just the fidelity gap."
Claude is right that dual-use funding matters, but the article understates policy and timing risk. Defense procurement cycles are lumpy, export controls can cap sales, and a single contract can vanish with a policy shift. Even if Infleqtion wins government work, scaling from lab-grade hardware to mass-manufactured, services-enabled platforms stays the bigger risk. Fidelity gap is real, but not the only gating factor; ecosystem, manufacturability, and revenue visibility matter more short-term.
The panel consensus is bearish on Infleqtion's prospects for outperformance against IonQ by 2026. Key concerns include the significant fidelity gap, the high burn rate in scaling neutral-atom hardware, and the risk of Infleqtion's government contracts not translating into faster quantum R&D funding.
