How to use a real hardware for VQE?

Hello everyone.

I have a question. Where can I see the tutorial for accessing any real hardware (for example, the IBM real backends) to run my VQE program that I wrote using Pennylane?

Thank you very much for the answer.

Hi @verstrikt,

You can learn about using our PennyLane-Qiskit plugin here in the docs. We’re working on making more tutorials that will make it easier for you to learn how to use this plugin. Give it a try by installing it with pip install pennylane-qiskit together with the latest PennyLane version and let us know if you run in to trouble or need some help!

Hi,

You have demos on how to use IBMQ via Pennylane:

If you have an error in the device about your account already exist you need to create a provider object and pass it to the divide. Like this:

from qiskit_ibm_runtime import QiskitRuntimeService

# For an IBM Cloud account.
ibm_cloud_service = QiskitRuntimeService(channel="ibm_cloud", token="MY_IBM_CLOUD_API_KEY", instance="MY_IBM_CLOUD_CRN")

# For an IBM Quantum account.
ibm_quantum_service = QiskitRuntimeService(channel="ibm_quantum", token="MY_IBM_QUANTUM_TOKEN")

Best
