When traders talk about the unreal intelligence (AI) market, they usually give attention to GPU makers like Nvidia, generative AI software program builders like OpenAI, AI-driven cloud giants like Microsoft, and knowledge heart and networking chipmakers like Broadcom. But these traders will usually overlook the potential AI tailwinds for the budding quantum computing market.
Quantum computer systems can course of binary bits of zeros and ones concurrently, whereas conventional computer systems course of these bits individually. That distinction allows quantum computer systems to course of bigger portions of information at a a lot sooner charge, however they’re nonetheless larger and costlier, and generate a better charge of errors than conventional computer systems. That is why they’re nonetheless not as broadly used to course of AI purposes as high-end knowledge heart GPUs.

However over the following few years, quantum computing corporations plan to miniaturize their chips, scale back their error charges, and make them cheaper to fabricate. They’re additionally offering extra of their quantum computing energy as cloud-based providers. These enhancements may make them way more helpful for demanding AI purposes.
Two quantum computing corporations which may profit from that development are IonQ (IONQ 10.84%) and Rigetti Computing (RGTI -4.90%). Let’s examine which of those early movers is likely to be a greater funding.
The variations and similarities between IonQ and Rigetti
IonQ sells three kinds of quantum computing methods: Its top-tier Aria quantum system, its commercial-oriented Forte system, and its on-premise Forte Enterprise system. It additionally gives its quantum computing energy as a cloud-based service. It primarily sells its services and products to massive authorities clients and universities.
It is also been growing a “trapped ion” expertise that might probably shrink the width of a quantum processing unit (QPU) from just a few ft to a couple inches. That miniaturization course of may pave the way in which towards the event of cheaper and extra highly effective quantum computing methods sooner or later.
Nonetheless, these efforts suffered a setback when its co-founder and chief scientist Chris Monroe — who had pioneered the trapped ion course of — unexpectedly stepped down final yr. But IonQ continued to develop after Monroe’s departure by putting in extra methods, signing new authorities contracts, and securing new AI partnerships.
Rigetti designs and manufactures its personal QPUs, and it lets builders write their very own quantum algorithms on its Forest cloud platform. That one-stop store mannequin makes it a “full stack” quantum computing firm.
Like IonQ, Rigetti additionally goals to develop cheaper and extra scalable QPUs for business clients. However Chad Rigetti, who based the corporate in 2013, stepped down as its president, CEO, and director in December 2022. That abrupt departure was alarming, however Rigetti subsequently allayed these fears with two main product launches.
Final December, Rigetti launched its Novera QPU, a 9-qubit business model of its personal quantum laptop, which prices $900,000. A number of main authorities and analysis clients have already ordered these QPUs. It additionally not too long ago deployed its first 84-qubit Ankaa-3 system, which is designed to detect greater than 99% of its processing errors, and it plans to deploy a extra highly effective 100-qubit system with an excellent larger error detection charge this yr.
Which firm has a brighter future?
IonQ and Rigetti each went public by merging with particular objective acquisition corporations (SPACs), and so they missed their rosy pre-merger estimates. IonQ solely generated $22 million in income in 2023, in comparison with its unique goal of $34 million. Rigetti generated simply $12 million in income in 2023, which additionally broadly missed its unique steerage of $34 million.
But each shares hit their all-time highs in December 2024 because the bulls applauded their latest progress. From 2023 to 2026, analysts anticipate IonQ’s income to develop at a compound annual development charge (CAGR) of 89% to $148 million, and for Rigetti’s income to extend at a CAGR of 43% to $35 million.
Each corporations are anticipated to remain unprofitable for the foreseeable future. IonQ and Rigetti may additionally maintain diluting their very own shares to boost money and canopy their stock-based compensation bills. IonQ has solely elevated its share rely by 10% since its SPAC merger, whereas Rigetti has boosted its share rely by 69% since its debut.
Each shares are richly valued. With an enterprise worth of $8.8 billion, IonQ already trades at 59 occasions its estimated gross sales for 2026. Rigetti’s enterprise worth of $4.3 billion is equal to a whopping 123 occasions its projected gross sales for 2026.
The higher purchase: IonQ
The quantum computing market may nonetheless broaden at a CAGR of 34.8% from 2024 to 2032, in accordance with Fortune Enterprise Insights, with smaller chips and extra environment friendly error detection charges. IonQ and Rigetti may gain advantage from that secular enlargement, however traders ought to be aware of their hovering valuations. I would not rush to purchase both of those speculative shares, however IonQ’s superior scale, larger development charges, milder dilution, and decrease valuation clearly make it a greater purchase than Rigetti proper now.
