How to Buy a Quantum Computer? Your 2025 Guide & Vendor List

Quantum computers have moved beyond the lab and are rapidly entering practical use, demonstrating transformative potential across industries like drug discovery, financial modeling, materials science, and logistics optimization. Yet, many are unsure where to find a quantum computer for sale or how to access computing services. This guide cuts through the confusion and walks you through your options step-by-step.

1. Buying Quantum Cloud Services

Purchasing a physical quantum computer is extremely expensive, which is why we start with quantum cloud services. (If you're specifically looking for a quantum computer for sale, skip to section 2.)

Quantum computing cloud services are the most mainstream and accessible way to use quantum power. You avoid the massive costs of buying and maintaining quantum hardware. Instead, you access real quantum processors (QPUs) and simulators hosted in the cloud. Typically, simulator access is often unlimited or very generous, while time on actual quantum hardware is usually billed. Major platforms include Amazon Braket, Microsoft Azure Quantum, IBM Quantum, and Origin Quantum.

Recommendation: For new users, Origin Quantum Cloud offers $165 worth of free QPU access time. This is an excellent way to quickly understand and experience real quantum computing. Click here to experience now: qcloud.originqc.com.cn/en/home

Cloud services are ideal for students, startups, researchers, and businesses wanting to leverage quantum computing without the prohibitive hardware costs.

2. Buying a Quantum Computer

Purchasing a full quantum computer system requires an enormous investment in hardware and ongoing maintenance. This option is realistically available only to entities with vast resources, such as national laboratories, top-tier research universities, major tech corporations, or large government-funded projects.

Key Vendors Offering Quantum Computers for Sale:

Origin Quantum

 A leading quantum computing company, Origin Quantum serves over 20 industries. Their superconducting quantum computer, "Origin Wukong," has been accessed over 30 million times. They offer consultations and sales for complete quantum computer systems and hardware. Direct Link: originqc.com.cn/en/

IBM

 Offers integrated quantum systems based on superconducting qubits (like the IBM Quantum System One and its iterations). They are one of the few commercial companies openly selling complete quantum systems, which include complex infrastructure like dilution refrigerators.

Google Quantum AI

Develops superconducting quantum processors. Their hardware primarily serves internal research and cloud platform access (Google Quantum Computing Service); direct sales of complete systems are rare and involve very high barriers to entry.

IonQ

A leader in trapped-ion quantum technology. While primarily accessed via cloud platforms (Braket, Azure, GCP), IonQ has begun delivering or plans to deliver physical systems to select customers (e.g., the US Air Force Research Lab).

Quantinuum 

Focuses on high-performance trapped-ion systems (H-Series). They provide cloud access and offer deep hardware access to strategic partners. Direct system sales are targeted.

D-Wave Systems

Specializes in quantum annealing (a form of specialized quantum computing). D-Wave has sold its annealing machines (e.g., Advantage systems) for years to clients including auto manufacturers, defense agencies, and research labs.

Key Considerations Before Buying a Quantum Computer

Before pursuing a quantum computer for sale, critically evaluate these factors:

1. Budget: Quantum computers represent a significant financial investment. Does your budget truly support this? If your goal is exploration or experimentation, cloud services (like Origin Quantum Cloud) offer affordable access to real hardware.
2. Core Need: Are you conducting fundamental quantum algorithm research, developing software tools, or aiming to solve a specific, classically intractable optimization or simulation problem? The answer dictates the type of system required.
3. Vendor Selection: Quantum technology maturity and performance vary significantly between vendors. Each excels at different problem types. There is no single "best" universal technology; your choice must align tightly with your specific application.

Conclusion

If you are determined to purchase a full quantum computer for sale, providers like Origin Quantum or IBM are primary options. Acquiring a complete system demands immense investment and requires thorough due diligence. However, if your primary goal is to experience quantum computing power, cloud services – particularly cost-effective options like Origin Quantum Cloud – are the highly recommended path forward.
