'qiskit.remote'/'qiskit.basicsim'/'qiskit.ibmq' is not working

Kshitij_Dave · November 4, 2024, 12:08pm

The backend showed me the output “<IBMBackend(‘ibm_brisbane’)>”.

from qiskit_ibm_runtime import QiskitRuntimeService
 
service = QiskitRuntimeService()
backend = service.least_busy(operational=True, simulator=False, min_num_qubits= 4)

dev = qml.device('qiskit.remote', wires= 4, backend=backend)

After running the qml.device for hardware/simulators show me this error:-

Hi @Kshitij_Dave, this looks like an issue with the environment where you’re running your code.

I recommended that you create a new virtual environment to avoid any installation issues. You can create a virtual environment with Conda and install PennyLane-Qiskit as follows:

Install Miniconda following the instructions here.
Open your terminal (mac) or command line (Windows).
Create a new Conda environment with: conda create --name <name_of_your_environment> python=3.10
Activate the environment with: conda activate <name_of_your_environment>
Install PennyLane-Qiskit with: python -m pip install pennylane-qiskit
Install other useful packages with: python -m pip install jupyter matplotlib

Note that you will be installing 3 packages here: PennyLane-Qiskit, Jupyter, and Matplotlib. Also, note that where it says <name_of_your_environment> you can choose any name that you want.

Once you have your environment I would recommend running something like the code below. Make sure to use wires=127 since IBM’s devices actually have 127 qubits.

import pennylane as qml
from qiskit_ibm_runtime import QiskitRuntimeService
QiskitRuntimeService.save_account(channel="ibm_quantum", token=token, overwrite=True)

service = QiskitRuntimeService()
backend = service.backend(name= 'ibm_sherbrooke')

dev = qml.device('qiskit.remote', wires=127, backend=backend)

Note that you might get a PennyLaneDeprecationWarning the first time you run this code, this is normal.

Let me know if this solves your issue!
