Quantum computers are not for sale to individual buyers, and commercial systems run between $10 million and $15 million for the hardware alone
If you are looking to buy a quantum computer for your home or small business, you will not find one on the market. Quantum systems are sold only to large organizations — universities, research institutions, and Fortune 500 companies — and the entry price is steep. A working quantum computer from IBM, IonQ, or Rigetti costs somewhere between $10 million and $15 million for the physical machine, plus another $1 million to $3 million annually for maintenance, staffing, and software licenses.
The actual cost depends on the number of qubits (the quantum equivalent of a classical computer's bits), the type of quantum processor, and what the buyer plans to do with it. A 50-qubit system costs less than a 1,000-qubit system. A machine built for pharmaceutical research may cost more than one built for optimization problems. There is no fixed price list because each sale is custom.
Key Takeaways
- Quantum computers are sold only to large organizations, not to individual consumers or small businesses.
- A working quantum computer costs between $10 million and $15 million in hardware, plus $1 million to $3 million per year in operating costs.
- Cloud-based access to quantum processors costs between $100 and $10,000 per month, depending on usage and the provider.
- Most organizations start with cloud access rather than buying hardware, because it requires no upfront capital and no on-site informed.
- The total cost of ownership includes not just the machine but also the engineers, physicists, and software developers needed to run it.
Why quantum computers cost so much
A quantum computer is not a faster version of a laptop. It is a specialized research instrument that requires extreme conditions to operate. The processor must be kept at temperatures near absolute zero — colder than outer space — which demands industrial-grade refrigeration systems. The qubits themselves are fragile and lose their quantum state if disturbed, so the entire machine must be isolated from vibration, electromagnetic interference, and heat.
The engineering required to build and maintain these conditions is expensive. A single quantum processor from IBM or IonQ is surrounded by dilution refrigerators, shielding, control electronics, and classical computers that manage the quantum operations. The facility itself — the building, power supply, cooling systems, and safety equipment — can cost millions before the processor is even installed.
Labor is the other major cost. Operating a quantum computer requires physicists with PhDs, quantum engineers, and software specialists. These roles are scarce and command high salaries. A single organization might employ 10 to 30 people just to keep one quantum system running and to help other teams use it.
Cloud access as an alternative to buying
Most organizations do not buy quantum hardware. Instead, they rent time on a quantum computer through the cloud. IBM Quantum, Amazon Braket, Microsoft Azure Quantum, and IonQ all offer remote access to their quantum processors. A researcher or engineer sends a job to the cloud, the quantum computer runs it, and the results come back in minutes or hours.
Cloud pricing varies by provider and usage. IBM charges between $100 and $500 per month for a subscription that includes a certain number of quantum operations. Amazon Braket charges per task — roughly $0.30 to $1.00 per task, plus $0.35 per second of per-task per-device time. IonQ charges between $500 and $10,000 per month depending on the number of qubits and operations needed. A small research team might spend $200 to $500 per month; a large organization might spend $5,000 to $10,000.
Cloud access has no upfront capital cost and no need to hire a full quantum team. The provider handles maintenance, upgrades, and staffing. This is why cloud access is the standard entry point for any organization considering quantum computing.
What you get for the money
The price of a quantum computer reflects what it can do — and what it cannot do yet. Current quantum computers are not general-purpose machines. They excel at specific problems: simulating molecular behavior for drug discovery, optimizing logistics networks, breaking certain types of encryption, and solving mathematical problems that would take classical computers thousands of years.
A $10 million quantum computer might solve one problem that a classical supercomputer cannot solve in a reasonable time. It will not replace your laptop or run your email. It will not speed up web browsing, video streaming, or word processing. The value is narrow and deep: if you have a problem that quantum computing can solve, the cost is worth it. If you do not, the machine is worthless to you.
This is why most buyers are pharmaceutical companies (simulating drug molecules), financial firms (portfolio optimization), and defense contractors (cryptography). Universities buy quantum systems for research, often with grants from the National Science Foundation or the Department of Energy. Small companies and startups almost always use cloud access instead.
The total cost of ownership over five years
Buying a quantum computer is not a one-time expense. The machine depreciates, breaks down, and becomes outdated. Here is what a five-year ownership scenario looks like for a mid-size organization:
| Cost Category | Year 1 | Years 2–5 (per year) | Five-Year Total |
|---|---|---|---|
| Hardware purchase | $12 million | — | $12 million |
| Installation and setup | $500,000 | — | $500,000 |
| Facility (building, power, cooling) | $2 million | $500,000 | $4 million |
| Staff (engineers, physicists, support) | $1.5 million | $1.5 million | $7.5 million |
| Maintenance and repairs | $300,000 | $400,000 | $1.9 million |
| Software licenses and upgrades | $200,000 | $200,000 | $1 million |
| Five-Year Total | $16.5 million | $2.6 million/year | $26.9 million |
Over five years, a quantum computer that cost $12 million to buy will cost nearly $27 million to own and operate. This is why organizations run a cost-benefit analysis before buying: they must be certain the machine will solve problems worth more than $27 million in value over that period.
Renting versus buying: when each makes sense
Cloud access is the right choice if you are exploring quantum computing, do not have a specific high-value problem yet, or want to avoid capital expense. You pay only for what you use, and you can stop anytime. A team of five researchers using cloud access for six months might spend $3,000 to $6,000 total.
Buying makes sense only if you have a concrete, high-value problem that quantum computing can solve, you plan to use the machine continuously, and you have the budget and staff to operate it. A pharmaceutical company running drug simulations 24/7 might justify the purchase. A university with a quantum research program might justify it with grant funding. A startup with an idea but no revenue should not.
Even large tech companies — Google, IBM, Amazon — do not buy quantum computers for internal use alone. They build them and sell or rent access to others, spreading the cost across many customers. This is the business model that makes quantum computing economically viable right now.
What quantum computers might cost in the future
Quantum hardware is improving faster than classical computers did at the same stage of development. Newer designs use different qubit types — trapped ions, superconducting circuits, photonic systems — each with different cost and performance tradeoffs. As manufacturing scales up and designs mature, hardware costs will fall. A quantum processor that costs $12 million today might cost $3 million in five years.
Software tools are also becoming cheaper and more accessible. Open-source quantum programming frameworks like Qiskit (from IBM) and Cirq (from Google) are free. As more engineers learn quantum programming, labor costs for quantum teams should decrease. Cloud pricing will likely drop as competition increases and providers optimize their infrastructure.
However, quantum computers will not become consumer devices anytime soon. They solve specialized problems that most people and organizations do not have. The cost will fall, but the machines will remain expensive, specialized tools used by research institutions, large corporations, and government agencies.
Frequently Asked Questions
Can I buy a used quantum computer?
There is no secondhand market for quantum computers yet. The technology is too new, too specialized, and too rapidly evolving. A used machine would be outdated within a few years. Organizations that retire quantum systems typically donate them to universities or scrap them rather than sell them.
Do quantum computers cost less if I build one myself?
No. Building a quantum computer from scratch requires informed in quantum physics, cryogenic engineering, and control electronics — skills that take years to develop. The cost of hiring the team and buying components would exceed the cost of buying from a manufacturer. Only large research institutions with existing physics departments attempt this, and it takes years.
What is the cheapest way to start learning quantum computing?
Cloud access is the cheapest way. IBM Quantum and Amazon Braket both offer free tiers with limited usage. You can write and run quantum programs for free to learn the basics. If you need more computing power, a paid subscription starts around $100 per month.
Will quantum computers ever be as cheap as regular computers?
Unlikely. Quantum computers solve a different class of problems than classical computers. They will not replace laptops or servers. As quantum technology matures, costs will fall and more organizations will have access, but quantum systems will remain specialized, expensive tools for specific applications.
Why does IBM sell quantum computers if they also rent access through the cloud?
IBM sells to organizations that need continuous, dedicated access and want to integrate quantum computing into their own research or product development. Renting works for exploration and occasional use. Buying works for organizations that have made quantum computing central to their strategy and can justify the cost.
