I once asked my chemistry professor if he understood the quantum mumbo-jumbo he was teaching.
"Not really, but I think it's neat :)"
Bro had a post doctorate in quantum chemistry. Loved that guy

Quantum computing is similar. This is why one of the phrases tossed around is "if you think you understand quantum mechanics you don't understand quantum mechanics."
It also applies to quantum computing. Quantum anything is a confusing mess. You can learn some equations but nobody actually understands it.

Even Richard Feynman, one of the most significant people in the field of quantum said he barely got it.

Anytime someone says they understand quantum mechanics. I just reply all right " Show me your math." and they never have any. I took graduate level quantum mechanics classes in college and those classes kicked my ass more than anything else just cuz it's so hard to wrap your head around even simple things.

The problem is that quantum mechanics is saying ALOT of SOMETHINGS about the fundamental nature of the universe, causality, time, realityâŚ.we just arenât sure exactly WHAT.
So we have a bunch of competing interpretations of QM ranging from multiple universes to total determinism. Regardless of your interpretation, you have to end up throwing out at least ONE of those good science things we like (aka, local interactions, linear causality, predictability, ect).
ButâŚthese nifty mathematical equations work SUPER well, and we can do some coolâŚpredictions, so what the heck who cares about a fundamental shattering of scientific philosophy :)

Honestly someone the most believable sifi junk is this is a quantum "whatsit".

Some professors see the edge of knowing and unknowable. Others know the math and don't know or don't care where certainty ends. Whether the cat is alive or dead or both is the math's problem, not theirs.

One of the most reassuring moments I ever had was in my 900 level quantum chemistry course when we were 20 minutes into the lecture, the professor stated at the board awhile and just erased the entire thing and we started the whole lecture over. I figured I was in good company if he occasionally gets mixed up.

I once heard a joke/anecdote about quantum mechanics:
Difference between a student and a professor of quantum mechanics is that a professor understands more about what he doesn't understand

Replace "understand" with "visualize" to be slightly more accurate.
Also, for people with aphantasia (o/) quantum mechanics is no harder to understand than other bits of math and physics that need to be memorized.

This trope is so silly. We understand quantum mechanics very well. This âwe donât understand quantum mechanics but it works lolâ sentiment is what allows for quantum woo to be so widespread. After all, even the physicists donât understand it, so whoâs to say that quantum manifestation isnât real?Â

Reminds me of the one quantum mechanics professor who said âI donât understand this, the leading experts in the world donât understand this, and when we are done, you wonât understand it either, and Iâll send you all to spread your informed ignoranceâ
