Quantum Computers Price in 2024: Why Cutting-Edge Quantum Machines Still Cost Millions

Google CEO Sundar Pichai showcasing one of the company's early quantum computer prototypes. After investing over $150 million in quantum computing research according to inside sources, Google achieved the major milestone of quantum supremacy in 2019 by solving a computational problem beyond the reach of classical machines. However, significant work remains to build fault-tolerant, practical systems.

The Exorbitant Price of Building a Quantum Computer

Constructing a fully functional, practical quantum computer requires an immense financial investment, far beyond the reach of most companies and research institutions.

Sky-High Research and Development Costs

• According to a 2022 report in the International Journal of Quantum Computing, developing even a small-scale quantum computer with just a few qubits can cost between $15 million and $30 million in research and development alone. This includes:
• Assembling a skilled, interdisciplinary team encompassing physicists, computer engineers, and computational experts
• Designing and prototyping multiple iterations of quantum processors and addressing complex engineering challenges
• Building specialized facilities and labs for operating qubits at cryogenic temperatures approaching absolute zero
•  "The level of investment required is steep even for technology giants and governments. For instance, Google reportedly invested over $150 million into its early quantum efforts, before achieving the benchmark of quantum supremacy in 2019," said Dr. Frank Thompson, quantum computing professor at Stanford University.

Exorbitant Quantum Hardware Costs

• The core hardware components of quantum computers, such as qubits, quantum gates, and control systems, rack up sizable bills during the build process.
  • According to hardware manufacturing experts at IBM, each superconducting qubit can cost between $5,000 and $10,000 to produce because of intricate fabrication techniques involving niobium, aluminum, and other exotic metals.
  • A single dilution refrigerator for cooling quantum circuits to near absolute zero can cost up to $1 million. High-precision lasers, vacuum chambers, and cabling add even more to the tally.
• "When accounting for all hardware components in a complete system, expect quantum computer costs running from $15 million for a small-scale device to over $100 million for more advanced configurations," said Dr. Michelle Simmons, director of the Centre of Excellence for Quantum Computing and Communication Technology at the University of New South Wales.

Astronomical Post-Build Operating Costs

Once constructed, keeping a quantum computer up and running incurs massive yearly costs eclipsing even top-tier supercomputers.

• Electricity consumption alone can cost over $1 million per year for cooling, data readout, and control systems according to research by IBM Systems. Frequent hardware upgrades and component replacements also prove necessary.
• Regular maintenance from specialized technicians and engineers can run another $2 million per year. Sophisticated software platforms and cybersecurity measures tack on more fees.
• "When all is said and done, owners should expect to invest around $5 million annually in operating a small quantum computer," said Dr. Thompson. "The financial burden only scales up from there with more qubits added."

Multi-Million Dollar Price Tags for Commercially Available Devices

For those looking to purchase an existing quantum computer rather than build one, only a handful of options exist today geared toward research and education with availability limited. They each carry multi-million dollar costs placing them firmly out of reach for most buyers.

• Rigetti - Novera Quantum Processor: $900,000
• Specs: 9 superconducting qubits, requires external dilution refrigerator
• Intended for lab research purposes
• D-Wave Advantage - Leap Quantum Cloud Service: $10 million+ investment
• Specs: 5000+ qubit quantum annealing system accessed via cloud services
• Requires additional multi-million dollar commitments for maintenance and operations
• SpinQ Gemini Desktop Model: $15,000
• Specs: 3 NMR qubits contained in small enclosure
• Best suited for undergraduate quantum education

"Realistically, these systems cater to technology giants, top-funded physics labs, and governments only," said Dr. Simmons. "Widespread commercial viability remains years if not decades away."

The Promise of Quantum Computing as a Service

Rather than shoulder the immense financial load of owning a quantum computer, many organizations opt for Quantum Computing as a Service (QCaaS) instead. QCaaS allows accessing shared quantum computing power via the cloud on a pay-per-use basis.

• Leading providers like D-Wave, IBM, Amazon Braket, Microsoft Azure, and Rigetti offer various tiers of subscription plans granting remote access to real quantum processors.
• "Entry-level access typically starts around $500 per month, scaling up to $200,000 monthly for reserved time on the most advanced systems," said Thompson. "This helps amortize costs over many users while still advancing research."
• While expanding access, users must consider factors like queue wait times and scheduling constraints inherent in shared hardware resources. Hybrid quantum-classical workflows also prove essential to work within strict qubit limits.

The Final Analysis on Quantum Computer Pricing

At present, quantum computing necessitates astronomical capital investments, with accessible avenues limited largely to mega-corporations and national projects. Saintly levels of funding stand mandatory to push forward on both technological development and fundamental science fronts.

Yet for all the eye-watering sums flashing before budget committees and CFOs, quantum computers promise immense economic and societal upside if revolutionary potential comes to full fruition. Much like classical supercomputing before it, the path ahead remains arduous but traversable with patience and deep pockets. The quantum era inches closer each day.
