Some Qiskit tutorials have aer_simulator in the code and I have noticed that this simulator is no longer available.

from qiskit import QuantumCircuit
from qiskit import Aer

Which of the existing simulators should I use to replace aer_simulator?

The example tutorial is here.


1 Answer 1


The aer_simulator was introduced in version 0.25.0 of Qiskit.

If it is not listed by Aer.backends() you should try upgrading Qiskit to the latest version.

You can use pip install qiskit --upgrade to install the latest version.
