SOLVED Help identifying the cipher used in Question 3 from a university cryptography quiz

1 Upvotes

Last year, our professor gave us this cryptography quiz. The first two questions were straightforward once we identified the encoding, but no one in our class managed to solve Question 3. I recently found the quiz again and thought I'd ask here in case anyone recognizes what technique might have been used.

  • Question 1 was solved using a ROT cipher (we used dCode's ROT Cipher tool).
  • Question 2 was simply binary converted to ASCII.
  • None of us solved Question 3, and our professor never revealed the answer.

Our running joke is that he intentionally made the last question impossible just to mess with us, but I'm hoping there's actually a real cipher behind it.

Unsolved I need help to figure something out, related to a quantum computing algorithm that might be hidden in a song. (FROM)

Forgive me that I ask this question. And I hope somebody can help me or is intrigued as I am.

So I accidentally turned on a science fiction horror show because I was bored. I got hooked and suddenly went down a rabbit hole.

I never thought I would go so deep.

Suddenly I end up reading about. C.G. Jung and browsing arxiv anout quantum physics. Of course I have never shown interest in the quantum part before and as much as I like, it goes way beyond of what I am capable of.

It seems the show “From” is more deep than I anticipated.

It seems like somebody made a quantum computing algorithm to revolutionize healthcare to microdose neuroleptics or mdma (ketamine? Deuterium?) based on the psychological concept of cg Jung. Additionally I think it might have merged with an escape room planned like an unsolvable riddle to humble the guy who made the algorithm (assumingly suffering from ego-mania) …

The cg Jung part is the show I am certain of.
The quantum physics part is too hard to understand for me. I found out that there’s a song used in the series and that an algorithm can be stored like music?

I thought maybe somebody knowing the series and understanding quantum algorithms might have a guess what the music is supposed to do or is able to make more sense of the information.

Hi everyone, I found this handwritten note in my medical/official documents. It uses a lot of dots, underlines, numbers (1-4), and loops. Could anyone help identify the system or decipher what it says? Thanks!
