`NoiseModelFromGoogleNoiseProperties` should raise an error when simulations use qubits not on the device or an uncompiled circuit

[NoureldinYosri]

Description of the issue
Noisy Simulation describes how to run simulations with realistic noise obtained from a real quantum device. however when using that noise model with a gate that is not native to the device the simulation, no noise gets added (e.g. #6607 (comment)). another issue is that when the circtuit uses qubits not on the device a key error is raised with little information explaining why that is.

Proposed Solution
Before (or while) running the simulation validate that the qubits and gets in the circuit uses supported qubits and gates.

How to reproduce the issue
#6607

Cirq version
1.4.0.dev20240419073809

Hi, I'm interested in taking on this issue. Will look more into the current implementation.

@shef4 thanks for offering to help

Hi @NoureldinYosri , please assign this issue to another developer. Thank you for learning opportunity. The cirq meetings are a great place for students to learn about real world development practices and I hope they continue to help new and experienced developers grow and learn.

Hi @NoureldinYosri Can i take this up

[NoureldinYosri]

@nivedha1 sure, thanks for offering to help

Hi @NoureldinYosri

I was able to implement the first part of the problem "To raise an error when trying to run simulations with qubits not on the device"

But for "A circuit not compiled to a supported gateset" part,

Im unable to figure out a way to get the target gateset from the compiled gateset to check if it is part of supported gateset.

Please Advise

Thanks!

Hi @nivedha1, from the comment made about this issue #6607 (comment) by cosenal

And in fact, CNOT (CXPowGate) doesn't even show up in the list from noise_props.expected_gates() 🤔

you might need you use this function to check which gates are supported by the device noise_props.expected_gates()
