How to run Fake Providers locally with QiskitRuntime

[ACE07-Sev]

Greetings,

Hope you are well. I am trying to get fake providers running for my wrapper, but have been having issues with defining the QiskitRuntime instance which is needed for the latest caliberations.

I have prepared a minimal example.

from qiskit import QuantumCircuit
from qiskit import transpile
from qiskit.visualization import plot_histogram
from qiskit_ibm_runtime import QiskitRuntimeService
from qiskit_aer import AerSimulator

# get a real backend from the runtime service
service = QiskitRuntimeService()
backend = service.get_backend('ibmq_manila')

# generate a simulator that mimics the real quantum system with the latest calibration results
backend_sim = AerSimulator.from_backend(backend)

# Create a simple circuit
circuit = QuantumCircuit(3)
circuit.h(0)
circuit.cx(0,1)
circuit.cx(0,2)
circuit.measure_all()
circuit.draw('mpl', style="iqp")

# Transpile the ideal circuit to a circuit that can be directly executed by the backend
transpiled_circuit = transpile(circuit, backend_sim)
transpiled_circuit.draw('mpl', style="iqp")

# Run the transpiled circuit using the simulated fake backend
job = backend_sim.run(transpiled_circuit)
counts = job.result().get_counts()
plot_histogram(counts)

And here is the error I am getting.

AccountNotFoundError: 'Unable to find account.'

I understand it's asking for an IBM Cloud account, but if I recall correctly the fake providers were supposed to be runnable locally without IBM Cloud account?

I am using Python 3.11.9, qiskit 1.1.0 (downloaded from the stable branch), qiskit_ibm_runtime 0.23.2, and qiskit_aer 0.14.2.

@ACE07-Sev to use QiskitRuntime, you need to initialize your account. Please refer to this page https://docs.quantum.ibm.com/api/qiskit-ibm-runtime/runtime_service#account-initialization

I see, thank you very much! May I ask how I can access all of the fake providers? I apparently can only access Kyoto, Osaka, Sherbrooke, and Brisbane.

@ACE07-Sev I am not getting this issue.

I guess you should try again configuring your work environment. Refer to this video https://www.youtube.com/watch?v=dZWz4Gs_BuI&list=PLOFEBzvs-VvrgHZt3exM_NNiNKtZlHvZi&index=3&ab_channel=Qiskit

No, I use QiskitRuntime to get the latest caliberations for the fake providers. You're apparently just importing the provider backends directly.

The fake backend from IBM Qiskit Runtime are in https://github.com/Qiskit/qiskit-ibm-runtime

So... moving it there.

Hi @ACE07-Sev, if you want to access latest calibration info of a backend, it will required an IBM Quantum/Cloud account. Otherwise, you can use the fake backends as mentioned in this comment
