Authentication

PasqalCloudConnection

To authenticate with PasqalCloudConnection, you need to enter the credentials of your account as well as a project ID you are a member of. The jobs created through the connection will then be billed to this project.

from pasqal_cloud import PasqalCloudConnection

project_id = "your_project_id"  # Replace this value with your project_id on the Pasqal platform. It can be found on the user-portal, in the 'project' section.
username = "your_username"  # Replace this value with your username or email on the Pasqal platform.

Method 1: Username + Password

Authenticate with your email and password directly:

password = "your_password"  # Replace this value with your password on the Pasqal platform.
connection = PasqalCloudConnection(username=username, password=password, project_id=project_id)

Warning

Never put your password directly in code. Use environment variables to avoid leaking passwords by mistake when pushing your code.

Method 2: Interactive

The password can be omitted from the arguments. You will be prompted to input your password directly in your terminal when running your script. This method is an alternative to setting your password as an environment variable when running your script manually.

connection = PasqalCloudConnection(username=username, project_id=project_id)

Method 3: Use a custom token provider (developers only)

You can define a custom class to provide the token. For example, if you have a token, you can use it to authenticate with our APIs:

from pasqal_cloud.authentication import TokenProvider

class CustomTokenProvider(TokenProvider):
    def get_token(self):
        return "your-token"  # Replace this value with your token


connection = PasqalCloudConnection(token_provider=CustomTokenProvider(), project_id=project_id)

Alternatively, create a custom TokenProvider that inherits from ExpiringTokenProvider. You should define a custom '_query_token' method which fetches your token. See Auth0TokenProvider implementation for an example.

OVHConnection

For OVH users, authentication is handled via the PASQAL_PULSER_ACCESS_TOKEN environment variable. No username or password is required.

export PASQAL_PULSER_ACCESS_TOKEN="your-access-token"

from pasqal_cloud import OVHConnection

connection = OVHConnection()
