Hello Pennylane Team,
I have problem with this documentation
https://docs.pennylane.ai/projects/rigetti/en/stable/devices/qpu.html

can you help me to solve this problem?
Code:

import pennylane as qml
dev_qpu = qml.device('rigetti.qpu', device='Aspen-M-2', shots=1000)

Error:

---------------------------------------------------------------------------

Hi @Dwi_Cahyo_Mariyanto ,

I think that device is no longer supported by Rigetti. The best way to access Rigetti devices is via the pennylane-braket plugin. I believe Rigetti has some new devices that are available via Amazon-Braket, although it’s best to check with the Amazon team since device availability changes over time. The Braket team also supports the plugin so you can let them know if you have any issues with it.

Hi @CatalinaAlbornoz

Thank you for your answer.
Actually I want to try Readout Error Mitigation from this Readout Error Mitigation Documentation pennylane-rigetti

Is the documentation still valid, because I have problem when running it?
