I am sort of realizing that in order to build solid intuition for Quantum Computing I really must dig deep into examples & existing algorithms in order to find the nuances that make things work and click together.
Some examples here I my recent attempts to revisit Grover and the QFT/invQFT algorithms:

- QFT: https://www.youtube.com/playlist?list=PLsedzcQz4wyXIxgF9zAv_G8_3SrZVjiye
Here is an example of something which I find really unintuitive about quantum computing: You are playing with waves & these waves do wave-things like creative & destructive interference. When you are phasing some elements of a superposition you are using interference but you can still manipulate the original superposition! -> check out my confused aha! moment at minute 37 here: https://www.youtube.com/watch?v=5sOdez49jT8&feature=youtu.be&t=2226
