Where to find Layer information (LDF) for generated quibit design

[Reece-Bird]

Hi there. I have generated a few qubit designs from the SQuADDs database and am wanting to do some simulations on them with a different simulator (My uni doesnt have ANSYS software). How would I go about getting this information from the database? I didnt see any methods to pull it from the design (Besides some default info that was inserted from the add_chip_info method in the DesignPlanar class from quiskit metal but I suspect this is wrong). Here is the chip qubit im currently working with (Im also not sure where its JJ is?)

Hi @Reece-Bird

Very happy to hear that you've been using our database!

Could you provide me a bit more information so that I can help you better?

• what simulator are you planning on using?
• for the JJ part, you are right it is not shown in the screenshot you shared. I would recommend following this tutorial.

Hi Shanto, thanks for the quick response, apologies if I have some stupid questions, I'm only just starting my journey into the quantum circuits industry (Final year electronics engineering student). I plan on using InductEx to calculate the capacitance and inductance matrices and then use the lumped oscillator model to calculate the Hamiltonian (I wanted to get some reference designs from your data base to use to check if my Hamiltonian is correct). I will have a look at that tutorial you sent me, may take me a little while to go through it! Thanks in advance for your help

Also while you are here could I perhaps trouble you with one other problem I'm now having. I have been working through tutorial 7 like you told me to (Thanks I didnt realize how useful it was). But I have come to a grinding halt on cap_sim.run(), I have been trying for little over 7 hours trying to get this working with no luck. To make things easier I have linked a video of me doing the whole setup (I edited it to make it brief), if you have any ideas please let me know. My best guess is it is trying to run an incompatible version of palace on my system (I use windows and it seems the debugger keeps getting stuck on the apple silicon method, _is_native_arm64() )
