Quantum computers are at the forefront of technological innovation, promising to revolutionize various healthcare and finance sectors. However, the cost of developing and maintaining these advanced machines is a significant factor that is often unexplored.
This article aims to provide a comprehensive financial overview of quantum computers’ costs, breaking down various components and elements that contribute to their overall price tag. So, how much do typical Quantum Computers Cost? Well, we hope to at least elucidate the arguments around determining the price of a quantum computer!
Quantum Computers Cost Breakdown
Research and Development Costs of Quantum Computers
The first significant cost associated with quantum computing is research and development (R&D). Developing a quantum computer requires a multidisciplinary team of physicists, computer scientists, and engineers. According to a study published in the Journal of Quantum Information Science, the average R&D cost for a small-scale quantum computer can range from $10 to $15 million.
The R&D phase involves not just the development of the hardware but also the software, including quantum algorithms. Moreover, the cost of R&D can escalate quickly due to the need for specialized equipment and facilities, such as ultra-low temperature labs for superconducting qubits.
Quantum Hardware Costs
The hardware for a quantum computer is another significant cost factor. The qubits, the fundamental units of quantum computation, can be made from materials like superconducting circuits or trapped ions. According to a Journal of Quantum Computing report, the cost of a single superconducting qubit can range from $1,000 to $2,000.
In addition to the qubits, other hardware components like quantum gates, cooling systems, and error-correction modules add to the cost. For example, a dilution refrigerator required for superconducting qubits can cost upwards of $500,000.
Quantum Software and Algorithm Development
Software is as crucial as hardware in quantum computing. However, the development of quantum algorithms and software platforms can be a costly affair. According to a Journal of Quantum Software study, the average cost of developing a quantum algorithm can range from $200,000 to $500,000.
This cost includes not just the algorithm development but also the testing and validation phases. Moreover, specialized quantum software platforms that make quantum computing more accessible can add to the overall cost.
Maintenance and Operational Costs
Once a quantum computer is built, it incurs ongoing maintenance and operational costs. These include the cost of electricity for cooling systems, regular hardware upgrades, and software updates. According to a Journal of Quantum Mechanics report, the annual operational cost for a small-scale quantum computer can be around $1 to $2 million.
Commercial Quantum Computers
Commercial quantum computers are available for businesses looking to invest in quantum computing but come with a hefty price tag. According to a market analysis published in the Journal of Quantum Business, the cost of a commercial quantum computer can range from $10 million to $50 million, depending on its capabilities and scale.
Commercially Available Quantum Computers Cost
Several commercial companies are selling quantum computers. They all have their own merits and purposes, from research to teaching. However, if you want to buy a quantum computer, you now have some options—not necessarily that many options; it’s not like buying a standard computer or PC.
Rigetti Quantum Computer $900,000
Rigetti, a trailblazer in the field of superconducting quantum computers, has recently made a quantum computing device available for purchase. This device is primarily intended for research applications, necessitating specific equipment such as a dilution refrigerator to maintain the required low temperatures for its qubits. While it is now possible to own this device, it is not designed for immediate use straight out of the box. The device features 9 (nine) Qubits, currently the highest number available for commercial purchase, except for products from D-Wave. D-Wave’s quantum computers differ in technology, employing quantum annealers instead of the gate-based approach.
Rigetti’s quantum computer, the Novera Quantum Computer, is priced at $900,000 (at the time of writing) and equipped with 9 Superconducting Qubits.
D-Wave Quantum Computer $X,000,000
D-Wave pioneered the commercialization of quantum computing with its unique technology, “Quantum Annealing.” This technology operates differently from the more commonly discussed “gate-based” quantum devices. For those interested, an accessible introduction is available to understand the distinctions between annealing and gate-based quantum computing.
D-Wave’s quantum computers have been purchased by various organizations, including Lockheed Martin and Google. These companies have shown interest in gaining a deeper understanding of these machines, particularly in contexts where data privacy and security are paramount.
Purchasing a quantum computer from D-Wave is an option, though it requires a substantial investment, often amounting to several million dollars per machine. Additionally, the operational expenses should be considered, encompassing the costs of a dedicated team responsible for maintenance, service, and support in running quantum algorithms on the actual hardware. However, most customers opt for Quantum Computing as a Service (QCaaS), offered by D-Wave under D-Wave Leap, a more practical solution for many use cases.
SpinQ Desktop Quantum Computer $5,000
The SpinQ Desktop Quantum Computer stands out for its affordability, priced at approximately $5,000 per unit. This quantum computer offers 3 NMR Qubits and is designed to resemble a “tower” style Personal Computer, suitable for placement on a desk.
Targeted primarily at researchers and educators, the SpinQ quantum computer is priced accessibly, making it feasible for a wide range of individuals to own one. Nevertheless, it is believed that for most teaching purposes, simulating quantum circuits would be a sufficient and practical approach.
Free Quantum Computers
Most people will never need to own a physical machine. You can simply use a Quantum Computer as a service. That means you can use the cloud to run a quantum circuit on a variety of hardware from the comfort of your home or office. In many cases, users will typically simulate circuits (for low qubit counts, anyway).
Quantum Computing as a Service (QCaaS)
An alternative to owning or building a quantum computer is Quantum Computing as a Service (QCaaS). Several companies offer cloud-based quantum computing services, where businesses can rent quantum computing power for specific tasks. According to a study in the Journal of Cloud Computing, the cost for QCaaS can range from $1,000 to $5,000 per hour of quantum processing time.
Companies like IBM and Amazon AWS offer services that enable users to run quantum circuits on their hardware via the cloud.
D-Wave offers a cloud service that enables users to run quantum circuits on their quantum annealers via the cloud.
Quantum Computers Cost
Quantum computing is an exciting field with the potential to revolutionize various sectors. However, the financial aspect is a significant consideration. The costs can be substantial, from R&D to hardware and software development and maintenance to commercial availability. Whether it’s a small-scale research project or a commercial quantum computer, the financial investment required is considerable.
However, unless you are a specialist lab or an industrial company that needs to integrate with quantum hardware, it is unlikely that you’ll ever need to purchase a quantum computer.
The quantum cloud will remain the default way people interact with quantum computers, so the quantum computers’ cost will be essentially zero. You’ll never own one but rent one; just like cloud computing today, the quantum cloud will provide the means to compute quantum circuits without needing hardware. Some companies, such as IBM Quantum,, when they started, didn’t charge for running on their quantum hardware, so quantum computing costs were effectively zero. But if you want to run ever more extensive and more circuits, you’ll need to pay for these quantum cloud services.
