How can I find and select the quantum backends available in qbraid?

Question

I'm using a qiskit tutorial for qbraid which is a basic hello world. I see that there is the possibility to use other quantum backends rather than qiskit, but there's not a clear path for this in the UI.

Is there a command line or direct way to search the API for other backends?

In the language of qBraid you are looking for ways to expose and select Devices. One of the advantages of qBraid as a platform is the ability to engage with a range of quantum computing platforms, and manage your workload, and they seem to have been adding more providers in the last six months or so.

The documentation for Devices shows methods for what they call "Unified Device Search". There is a get_devices function that returns the platforms as well as their status.

from qbraid import get_devices

get_devices()

They give examples of running this function with search criteria, such as "search for all gate-based QPUs with at least 7 qubits".

get_devices(
    filters={
        "paradigm": "gate-based",
        "type": "QPU",
        "numberQubits": {"$gte": 7},
    }
)

This call in Jupyter has a neat table return, and qBraid sidebar.

Be sure to check the docs for examples on wrapping these devices and managing workloads.
