I have a bachelors in physics but I wasn't a great maths student in university (the folly of youth) so my linear algebra could be better. On the other hand, I'm not going to redo linear algebra as a pre-requisite for this course. I also haven't done the pre-requisite QC courses, though I'm much more comfortable in that domain.

I don't use ChatGPT to teach me the concepts in the course, I use it as an empathetic tutor to fill in the blanks. If I see a linear algebra identity I'm not familiar with I can ask ChatGPT, telling it the context and what I already know and it'll give me an answer in that context with solid mathematical grounding but (because I ask for it) intuitive justifications. The alternative of stackoverflow, wikipedia, or other online notes can be hard to search for and even when I find a good answer, it's often needlessly mathy and complex. I don't have to worry about hallucination because it is just a gap and once I understand it, usually what the lecturer said makes perfect sense.

In one lecture the lecturer had a throw-away line about stabilisers corresponding to syndrome measurements but didn't elaborate much further. I didn't get how the corresponding circuit would be constructed so I went to ChatGPT and asked it my question with what I knew and the context. In that case, it pushed back and told me that what I knew was wrong. I had formed a misconception which it corrected and gave me an example to show why I was wrong.

I guess I don't use it as a lecturer, or even a tutor. I use it as the really smart guy you sit next to in a lecture theatre who you whisper questions to.
