VTT QX quantum cloud service description

VTT hosts a 50-qubit superconducting quantum computer, VTT Q50. The quantum computer is open for companies for running and developing their own algorithms.

VTT QX quantum computing service is implemented as a cloud service, providing users access to VTT’s quantum computer. The service is offered without any service level definitions. Users can run quantum circuits, manage their jobs, see previous results and view specific device metrics through the platform.

VTT QX provides user management, project management and access management, along with documentation on job submission.

Financial and contractual constraints

  • The service is subject to a written contract between VTT and customer. The onboarding process starts upon contract signature and may take some time.

  • Customer defines named users to access the service, who get access right via email. Additional users can be added later.

  • Customer can define maximum monthly or total quota in a single project by submitting request to the service support portal.
  • Quota is measured in QPU seconds, produced by the electronic control stack and computed from execution end time – execution start time. This represents the pure quantum processing time consumed on the hardware, excluding queue waiting time and compilation overhead.
  • For jobs submitted during the booking period, the platform don't count the entire period towards QPU usage, it will count towards the booking minutes quota. This approach accounts for the opportunity cost of reserving quantum resources while preventing double counting of usage metrics.

  • The service is provided “as is”, no SLA is given unless specifically agreed. Service can be unavailable without prior warning any time. 

Pricing

  • Price €0.40 / QPU second. Minimum charge €1,000 / month. All prices are excluding VAT.

  • Pricing of the service is based on realised computing time in QPU seconds, failed quantum jobs are not counted.

  • Monthly invoicing based on last month’s realised QPU seconds, with a minimum invoicing per calendar month. Invoicing starts when VTT QX access codes are sent to users.
