Quantum Computing Companies of 2026

Quantum computing, which has wide-ranging applications in optimization, research, and cryptography, is driven by these organizations:

• End-to-end solution providers
• Quantum hardware builders
• Software & services companies
• Research labs
• Companies that use quantum computers in their business (Not the focus of this article)

Quantum hardware is an emerging computing technology that relies on complex hardware. As in the early days of personal computing, there are companies specializing in hardware, software, and end-to-end solutions.

In the early days of computing, Apple built end-to-end solutions, while Microsoft specialized in software, and many OEMs and IBM (Original Equipment Manufacturers) specialized in hardware and services.

In addition to these, research labs (like the Bell Labs during the personal computing revolution) play an important role in driving research.

Investment overview

The quantum computing industry experienced unprecedented investment growth in 2025, marking a critical inflection point from theoretical research to commercial deployment.

Key statistics:

• Quantum computing companies raised $3.77 billion in equity funding during the first nine months of 2025.
• This represents nearly 3x the $1.3 billion raised in all of 2024
• Two late-stage startups (PsiQuantum and Quantinuum) captured approximately half of all 2024 venture funding.
• European startups captured 47.5% of quantum venture funding in Q1 2025, up 16.5% from the previous year.
• Hardware development now dominates funding rounds, reversing the software-heavy pattern of 2023-2024.
• JPMorgan Chase announced a $10 billion strategic technology fund that specifically identifies quantum computing as a priority investment area.

Market projections:

• Global quantum computing market: $1.8-3.5 billion (2025) to $5.3-20.2 billion by 2029-2030 (CAGR 32.7-41.8%).
• McKinsey projects that quantum technologies could generate up to $97 billion in revenue worldwide by 2035, with quantum computing accounting for $72 billion.

What are the different types of quantum computing companies?

End-to-end solution providers

Tech giants, IBM, Google, Microsoft, NVIDIA, and growing start-ups Rigetti and D-Wave can be considered end-to-end providers. These companies enable other companies to test quantum solutions on cloud.

• NVIDIA’s CUDA-Q Framework provides quantum-classical hybrid computing integration, enabling seamless GPU-QPU workflows. Partners include Alice & Bob, Anyon Computing, Atom Computing, Diraq, Infleqtion, IonQ, IQM, ORCA Computing, Oxford Quantum Circuits, Pasqal, Quandela, Quantinuum, Quantum Circuits Inc., Quantum Machines, Quantum Motion, QuEra, Rigetti, SEEQC, and Silicon Quantum Computing.

• D-Wave is the first company to sell a quantum computer to an American defense company, Lockheed Martin.
• IBM provides cloud access to test quantum algorithms developed with IBM-Q.
• Microsoft provides cloud quantum computing as Azure in collaboration with IONQ, Honeywell, and QEI.
• Google, Alibaba, D-Wave, and Rigetti provide end-to-end services.
• Amazon launched Braket in partnership with D-Wave, IonQ, and Rigetti.

Hardware systems builders

Companies interested in quantum hardware often work to optimize quantum computers and create simulation environments. Tech giants offering end-to-end solutions are included here as well. The hardware side of quantum computing can be separated into two:

• Universal gate-based quantum computers (also called general-purpose quantum computers)
• Quantum Annealing.
