Quantum computing stocks sit at the crossroads of advanced research and real world problem solving. This is why this Quantum Computing Stocks screener can be a useful starting point. While inflation trends, central bank decisions, and uneven growth data keep broader markets focused on interest rates and yields, quantum computing companies are working on hardware and software that could help tackle complex tasks across sectors. This article highlights 3 stocks from the screener so you can see how different business models approach the same long term theme and decide which, if any, deserve a place on your watchlist.

IonQ (IONQ)

Overview: IonQ is a quantum computing company that sells access to its trapped ion quantum computers, both directly and through major cloud platforms such as AWS, Microsoft Azure and Google Cloud. It also provides quantum safe communications, quantum detection systems and bespoke hardware, support and consulting contracts that help customers build and run algorithms on its systems.

Operations: IonQ currently generates its US$187.1 million in revenue from Computer Services, with most revenue from the United States at US$122.4 million, followed by Other International at US$37.2 million and Switzerland at US$27.5 million.

Market Cap: US$11.9b

IonQ has turned its core physics into a selling point, with trapped ion machines targeting high reliability and now a fully integrated hardware stack after completing the SkyWater acquisition in July 2026, which brings a domestic semiconductor foundry in house. Revenue is forecast to grow strongly while the company recently reached profitability. However, earnings are expected to weaken and the stock trades on a rich valuation, which underlines execution risk and the possibility of volatile results. Governance questions also linger, from high CEO compensation to recent board turnover and shareholder dilution. For quantum focused investors, the real question is whether this combination of vertical integration, cloud access and a large cash position can outweigh these red flags over the long run.

IonQ’s vertical integration and rich valuation could be telling two very different stories about its future potential. Get the full picture with the 2 key rewards and 4 important warning signs (3 are major!)

GLOBALFOUNDRIES (GFS)

Overview: GLOBALFOUNDRIES is a contract semiconductor manufacturer that produces chips such as processors, radio frequency components and power management units for customers in sectors like mobile, automotive, communications and data centers, and it is also building quantum technology solutions through partnerships such as its work with the U.S. Department of Energy’s Genesis Mission.

Operations: GLOBALFOUNDRIES generates its US$6.8b in revenue from its Semiconductors segment.

Market Cap: US$27.4b

GLOBALFOUNDRIES provides exposure to the demand for automotive, AI and communications chips, while also tying into U.S. manufacturing and quantum initiatives through recent CHIPS Act awards and its Quantum Technology Solutions push. Government backed funding of around US$300 million for silicon photonics, a new dividend, and expectations for earnings growth that outpaces revenue growth indicate a focus on higher margin niches rather than pursuing every chip cycle. At the same time, reliance on debt funding, limited exposure to the most advanced process nodes and customer pricing pressure keep risk firmly on the table. The key consideration is how these trade offs compare once you look past the headlines and into the detailed forecasts and risk checks.

GLOBALFOUNDRIES is focusing on higher margin niches and newly awarded CHIPS Act funding, yet the full story on risks and upside often sits beneath the headlines. See how the trade offs stack up in the 4 key rewards and 1 important warning sign

Xanadu Quantum Technologies (TSX:XNDU)

Overview: Xanadu Quantum Technologies is a Toronto based photonic quantum computing company that offers cloud access to its x series quantum devices and supports users with software tools for quantum programming, simulation and machine learning. Its Pennylane and Catalyst platforms aim to let developers plug quantum workflows into familiar Python and AI tools while drawing on support from Xanadu’s in house quantum specialists.

Operations: Xanadu Quantum Technologies generates CA$6.8 million in revenue from Computer Services, with most revenue from the United States at CA$5.8 million, followed by Canada at CA$0.5 million and the Rest of World at CA$0.4 million.

Market Cap: CA$4.1b

Xanadu Quantum Technologies offers pure play exposure to photonic quantum computing and software, with revenue growth of 223% over the past year and forecasts of further top line expansion. At the same time, the company is still loss making. Earnings are expected to decline by an average of 25.3% a year over the next 3 years, and the P/B ratio of 12.6x sits well above Canadian software peers, which highlights valuation and funding risk. Recent partnerships with Lockheed Martin, Mitsubishi Chemical, the U.S. Air Force Research Lab and EV Group, plus rapid U.S. footprint expansion, indicate growing commercial interest. The key question for investors is whether that momentum can eventually offset continued losses, share price volatility and a young board.

Rapid revenue growth and big photonic ambitions at Xanadu Quantum Technologies sit beside continued losses and a premium P/B. See how that tension plays out in the 2 key rewards and 3 important warning signs (2 are major!)
