Which statement describes the current availability of Quantum Computers?


Quantum computers are owned by some companies, but available to many.


In the realm of quantum computing, we find ourselves amidst the nascent stages of its evolution. Nevertheless, some entities and scholars have already harnessed its power for particular endeavors. Take, for instance, the case of Google AI, which delves into the intricacies of quantum computing to forge innovative machine learning algorithms. Concurrently, IBM extends an invitation to access its quantum computational resources via its cloud-based computing platform.

While the availability of quantum computers continues to be somewhat limited on a broader scale, diverse pathways for their utilization do exist. Companies and researchers, for instance, have the choice to either procure their own quantum computers or, in an alternative approach, gain access to these cutting-edge computational systems through leasing arrangements provided by cloud computing services.

Current availability of quantum computers

The following are some examples of how quantum computers are currently available:

  • IBM Quantum Cloud Services: IBM offers access to its quantum computers through its cloud computing platform, IBM Cloud. This allows anyone with an IBM Cloud account to access quantum computers for a fee.
  • Google Quantum AI: Google AI offers access to its quantum computers to a select group of researchers and companies.
  • Rigetti Computing Quantum Cloud Services: Rigetti Computing offers access to its quantum computers through its cloud computing platform, Rigetti Quantum Cloud Services.
  • D-Wave Systems: D-Wave Systems offers access to its quantum computers to a select group of customers.

Moreover, beyond these commercially accessible solutions, a myriad of academic and government institutions are actively involved in propelling the frontier of quantum computing. These entities predominantly focus on utilizing quantum computers for research purposes, yet there are occasions where they might offer restricted availability of quantum computers to commercial users striving to leverage the potential of quantum computing technology.

Availability of quantum computers for different types of users

The Availability of quantum computers to various user categories can be succinctly encapsulated in the following manner:

  • Companies: Companies can purchase their own quantum computers, lease access to quantum computers from cloud computing providers, or participate in a research program that offers access to quantum computers.
  • Researchers: Researchers can access quantum computers through commercial offerings, research programs, or by developing their own quantum computers.
  • Individual users: Individual users can access quantum computers through cloud computing platforms, but this is typically limited to small tasks.

Challenges Hindering the Access to Quantum Computers

Even with the notable advancements in quantum computing over recent years, several hurdles need resolution before quantum computers can be extensively accessible. The key obstacles encompass:

Qubit Decoherence:

Qubits are highly susceptible to their surroundings, and even minor disruptions can strip them of their quantum attributes. This issue, termed decoherence, stands as a major impediment in the construction of practical quantum computers. Researchers are devising various methods to alleviate decoherence, yet it remains a significant barrier.


For real-world applications, quantum computers necessitate a substantial number of qubits. However, creating quantum computers with a large qubit count sans errors is exceedingly challenging. Researchers are exploring novel approaches to scale quantum computers, presenting a formidable problem.

Hardware Development:

Specialized hardware is essential for quantum computers, which is presently not widely accessible and notably expensive to manufacture. Consequently, quantum computers are currently limited to a select few researchers and companies.

Software Development:

Quantum software is still in its early developmental phase. Quantum algorithms diverge significantly from classical algorithms, demanding new programming languages and tools. This poses a challenge for software developers and quantum computing researchers alike.


Presently, constructing and operating quantum computers incur substantial expenses due to intricate hardware and the necessity for specialized cooling systems. Consequently, quantum computers remain uneconomical for most applications.

In spite of these obstacles, researchers are swiftly advancing in quantum computing. Forecasts suggest that quantum computers will progressively gain power and affordability in the near future. Nevertheless, it’s crucial to be realistic about the challenges that must be addressed before widespread availability of quantum computers.
