Execution on IBM Quantum Cloud

The Classiq executor supports execution on IBM simulators and hardware.


Execution on IBM Simulators

from classiq.execution import IBMBackendPreferences

preferences = IBMBackendPreferences(backend_name="Name of requsted quantum simulator")

The supported simulators are fake hardware simulators.

Execution on IBM Hardware

Execution on IBM hardware requires a valid IBM Quantum API access token, and access to the requested hardware with an IBM Quantum hub, group, and project name. The access token is the API token that appears at the top of the IBM Quantum Platform page, when you are logged in. You must create an account with IBM quantum if you do not have one already.

The hub, group and project default values refer to the open access quantum systems, and are:

  • hub = "ibm-q"
  • group = "open"
  • project = "main"

However, you may have your own hub, group, and project values through your organization. For more information, see this FAQ.

from classiq.execution import (

ibm_provider = IBMBackendProvider(
    hub="Hub name", group="Group name", Project="Project name"
preferences = IBMBackendPreferences(
    backend_name="Name of requsted quantum hardware",
    access_token="A Valid API access token to IBM Quantum",
