Deprecated code in tutorial/notebook "Design 100 qubits programmatically"

[koloneltedi]

Expected Behavior

When executing block [17] of the notebook "Design 100 qubits programmatically" (link: https://qiskit.org/documentation/metal/tut/2-From-components-to-chip/2.22-Design-100-qubits-programmatically.html), one would expect the output to be as in the notebook.

Current Behavior

The following error-message: "This method is deprecated. Change your scripts to useanalysis.quantitative.capacitance_lom.run_lom(). This is logical since this is exactly what the source-code of the method currently says."

Steps to Reproduce

Follow the notebook.

Detailed Description

Presumably one could rewrite the tutorial with the method descibed in the error-message (useanalysis.quantitative.capacitance_lom.run_lom()). However I haven't found any documentation or source for that method, so am not sure what to exactly propose there. When looking ahead to future tutorials, I saw that block [14] of tutorial "Capacitance matrix and LOM analysis" (link: https://qiskit.org/documentation/metal/tut/4-Analysis/4.01-Capacitance-and-LOM.html) gave similar output to what was expected. Now I haven't run that tutorial yet (I'm just beginning with Metal), so am not sure if that is exactly the same or whether it works, but that seems to solve it.

Possible Implementation

Thanks for dropping the issue. Any chance you want to make a pull request with the fix?

[koloneltedi]

I'd love to! Will not be in the coming few days though, since I realized that my current Ansys license doesn't seem to support q3d, so I can't do the necessary testing. But once I fixed that I will look into it. I'll probably just follow a piece of code from tutorial 4.1, LOM part, and get something along those lines in this notebook. So if you don't mind the time-delay, I'll be looking forward to working on the fix. Seems like a good practise for contributing some new qubit components and such.

Great to hear, yes, no worries on the time. Looking forward to your pull request

I finally got to it, hopefully it is a stepping stone for any 'real' code contributions to come haha
