Can I use the quantum annealing or Ising machines other than the standard machines?

If you wish to use a machine other than the standard machines supported by the Fixstars Amplify SDK (Fixstars Amplify AE and D-Wave machines), please prepare a subscription agreement with the provider of the machine.

What is the price of using the cloud?

Fixstars Amplify can be used free of charge for trial and pilot purposes for the enterprises, and research & development purposes for universities and other educational institutions.
For the enterprises to use for business and commercial purposes, a paid plan, Standard plan or Premium plan, is required. Please visit the pricing page for more details. We also offer Academic plan for universities and other educational institutions who wish to use a more advanced computing environment. Please contact us for details.

What is the definition of the "user" in indivisual plans?

It means an individual who has registered as a user with Fixstars Amplify.

Do you offer an academic plan?

Yes. Although a Basic plan (free) can be used for research & development purposes at universities and other educational institutions, an Academic plan (paid) is also available for those who would like to use premium computing environments. Please contact us for details of academic plans.

For multi-user plans (up to 5 users) of indivisual plans, is it possible to change or add users to the plan during the contract period?

Yes, you can change the member of the users registered to your multi-user plan of indivisual plan at any time. Also, additional users may be added at any time asl long as it does not exceed a total of 5 users.

In what situation do we subscribe to business plans?

When a developer has completed the development and validation of a system or an application that incorporates Fixstars Amplify and is ready to go into production for use by multiple users in the division, the Business Plans can be the best fit.

Once the development of the program that incorporates Fixstars Amplify is completed and program is used in the production, do I only need a business plan and will no longer need an indivisual plan?

Yes, that is correct. However, if a developer continues to develop or prototype other programs, etc., the developer will continue to use the individual plan.

What is the definition of "division" in business plans?

We intend for it to be a department such as "Production Management Division" or "Production Engineering Department" that will share the use of the system or application. Please contact us if you have any questions.

If the same program would be used in the different divisions, does each division have to have the separate business plans?

Yes, it does.

It seems that the business plan may have a limit on the "total number of executions" per month. Where can I check my monthly "total number of executions"? Also, what should I do if I have exceeded or am about to exceed that "total number of executions"?

If you subscribe to a business plan, the representative person must be registered as a user with Fixstars Amplify, and a token will be issued to that representative person. You can check the "Total Execution Count" on the Resource Usage page of the representative's My Page.

We are planning to set up an option to add more executions to the total number of transactions per month, in case the total number of transactions per month is exceeded or about to be exceeded. We will announce the release of this option on our website.


Is the subscription monthly or annual?

Contracts must be made on a monthly basis, for the necessary number of months.

Is there a minimum contract period?

There is no minimum contract period for indivisual plans. Contracts can be made from one month. The minimum contract period for business plan (per division) is 3 months.

What does "for commercial use" on the pricing page mean, which requires having a paid plan?

Another example is to deploy the system embedding the program developed using Fixstars Amplify into the production environment. Also, in case we conduct a paid Proof of Concept (PoC), a paid plan is required. Please consult the Terms of Use for further details.
