Quantum Computing is a development-stage business with limited revenue. Commercial and government customers pay it for hardware and professional services, often starting with small exploratory projects to test quantum-based solutions. These include proof-of-concept work and research and development services. Its Dirac quantum computers address optimization problems and are available through cloud access or installations at customers’ premises; several technologies remain in early commercialization.
The business also supplies components that generate, detect or control light. Its acquired subsidiary, Luminar Semiconductor (LSI), sells photonic semiconductor devices and optical assemblies to aerospace and defense, sensing and instrumentation, and optical communications customers, alongside design, testing and consulting services. Quantum Computing plans to offer custom thin-film lithium niobate optical chips through its AZ Chips Facility foundry services.
Expanding sales depends on developing more capable products, demonstrating their value to customers and moving beyond small projects into larger-scale production. Its public-cloud services run predominantly on Amazon Web Services. U.S. export controls and sanctions restrict some overseas sales and require licenses or approvals for some products and technologies.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Quantum Computing's results hinge on turning photonic chips and quantum hardware into sales, with privately held PsiQuantum another quantum-computing rival to watch beyond this list.
D-Wave Quantum competes for customers using quantum computers to solve optimization problems, offering annealing systems and paid cloud access against Quantum Computing's Dirac photonic computers. Watch D-Wave's system sales and cloud-access revenue for evidence of customers paying for quantum optimization.
Xanadu and Quantum Computing both develop photonic quantum computers, but Xanadu targets fault-tolerant systems while Quantum Computing's Dirac products use entropy-based optimization. Watch whether Xanadu moves beyond its limited services, sponsored-research and early commercial revenue: in the year ended December 31, 2025, it had not achieved sustained commercial revenue from utility-scale quantum computers.
IonQ competes with Quantum Computing by selling quantum hardware, access to its computers and related services, with overlapping networking, sensing and security offerings. Its sales of specialized systems to customers including government agencies offer a concrete way to track demand in markets Quantum Computing also serves.
Infleqtion competes with Quantum Computing for government, research and commercial customers buying quantum computers and sensing hardware. Watch its Sqale system sales and government-funded development contracts for signs of spending on quantum computing and sensing, rather than treating its still-early cloud service as established demand.
Rigetti Computing offers superconducting quantum systems and paid computing access to customers also considering Quantum Computing's photonic systems and services. Watch whether processor sales and recurring computing-access revenue gain ground against technology-development contracts, which supplied most of Rigetti's revenue in the period described as current in its fiscal 2025 filing.
Quantinuum combines quantum computers with application software to compete with Quantum Computing for enterprise and government uses. Watch its customer work in financial-risk simulation and electronic-structure calculations for progress toward useful applications, though the supplied material does not say how those customers pay.
IonQ, Inc. earningsIONQ
IonQ's report will show whether government and other customers are buying specialized quantum systems, offering a demand signal for markets Quantum Computing also serves.
Watch IonQ's specialized-system sales and sales to government customers. Stronger sales would show that customers are spending in markets for quantum-system applications, offering a demand signal for Quantum Computing's government, sensing and networking work, but not evidence that orders will go to Quantum Computing. Weaker sales would point to cautious customer spending, leaving Quantum Computing's own contracts to prove demand for its related products and services.
D-Wave Quantum Inc. earningsQBTS
D-Wave Quantum's report will show whether customers are paying for quantum optimization systems and cloud access, a market Quantum Computing also targets with its Dirac products.
Read D-Wave Quantum's system sales alongside paid cloud access. Growth in both would show customers paying for quantum optimization and provide evidence of demand in a market Quantum Computing targets with Dirac, but it would not prove that Quantum Computing is winning orders. Weakness in both would mean commercial demand remains hard to establish; similar technology alone would not show that Quantum Computing can attract buyers.
Quantum Computing Inc. earningsThis company
Quantum Computing's report will show whether off-the-shelf hardware sales can grow while the company controls the cost of making and delivering those products.
Read product revenue alongside services revenue, then compare gross margin—the share of revenue left after direct costs. In 2025, product revenue rose but gross margin fell from 30% to 10%; the company said higher-than-expected labor to assemble and test the first unit of a new hardware product was a main reason. Product revenue growing with a recovering margin would show sales expanding as costs come under control; stalled product revenue and a still-thin margin would show that sales remain limited and hardware economics are not yet established.
