Quantum Computer Markets: Who Leads?

    Report

  • September 2025
  • Region: Global
  • Inside Quantum Technology
  • ID: 6173302

In this report the analyst provides 12 strategic profiles of distinguished firms around the world working to provide the quantum computer market with full-stack quantum computers and compare them according to a new rating scheme the analyst has constructed. The assessment approach scheme is unique in that it takes into consideration more than just technical benchmarking and appraises the companies considered on other factors that are just as important to long term business success.

These factors include: how the firms are viewed by the competition, cloud support and access, software, intellectual property, technology, acquisitions and business development, user communities and marketing efforts, customers and sales, technology and form factors and deployment. Each of the profiles includes a section in which they provide their opinion on the pros and cons of the companies that they are analyzing.

Using the assessment process involving the most important of these factors they have come up with the top four quantum computer companies currently operating in North America, Europe and Japan. And as an added bonus they include a thorough analysis of the quantum cloud sector and pricing of both the cloud services and (as far as possible) the machines themselves.

This report will be highly valuable to quantum hardware and software makers, the investment community, journalists and quantum users themselves.
