Number of device executions

Running this tutorial and the number of device executions with the qiskit.aer device yields zero in the latest version of Pennylane which is different to the outputs shown in the notebook.

If the device is swapped out for default.qubit the code is functional.

Any ideas why the output locally is different to the results shown in the tutorial?

Thanks a lot,

Hi @Zohim_Chandani1!

Sorry we took some time to respond.

I ran the demo with pennylane version 0.20.0, pennylane-qchem version 0.19.0, openfermion 1.1.0 and cirq 0.11.0

With these versions the only change I had to make in the tutorial was to change the device from ibmq_16_melbourne to ibmq_bogota since melbourne is not available anymore.

Otherwise the demo worked just fine.

I would suggest updating the version of the libraries using pip install <library-name> --upgrade .

Please let me know if this fixes your problem!
