Credentials & Linked Accounts

At present, Nexus offers support for working with Quantinuum Systems. If you want to learn more about backends before continuing with this guide, please review our backends page. Submitting to Quantinuum Systems devices works without any extra setup, using the Nexus account you’re signed in with to submit to hardware, but you can manage multiple accounts by adding their credentials to your Nexus account.

Managing credentials is all done through the ‘Backends’ tab.

The devices displayed on the ‘Backends’ tab are pulled from hardware providers where you have configured your credentials, you will know your credentials are configured correctly when the devices from that provider are visible in the ‘Backends’ tab.

Use ‘Manage Linked Accounts’ to view the credentials configured for your account.

Managing Quantinuum credentials

If you have a plan that includes access to Quantinuum Systems, you do not need to do anything to submit to this hardware (you can review your plan access at https://nexus.quantinuum.com/settings/organization). However, if you maintain multiple accounts you can manage all of them via Nexus. To support multiple sets of Quantinuum credentials you must also add the credentials for the account you’re currently signed in on, otherwise whichever account you add will be marked as the default option and you won’t be able to choose to use the credentials you’re currently signed in with.

Quantinuum credentials consist of a User Name and password pair, these are the same credentials that are used to sign in to nexus.quantinuum.com. Quantinuum credentials that are added to Nexus cannot have MFA enabled.

A Quantinuum account might not have a User Name or password if it was created using SSO, in which case it cannot be added as a set of credentials.
