    Very nicely done video! However I don't see how this connects to the intial problem of finding the key that fits, if you need to know which key fits in the beginning then what's the point? Clearly I'm missing some crucial detail.

    Good video but one thing I'm slightly unsure about was that in the representation of the probabilities the average value accross which the reflection is done changed as you reflected the correct solution. However in the angle model after, the reflection was done about the previous phi which did not change when the correct values reflection was done

    Sorry, with all due respect, I had to dislike your video like all other videos about Grover's Algorithm. It looks like nobody knows how to explain it for others to understand. It makes me think that you don't understand it either.

      @@lillianjiang4812very often when people go for an easy or intuitive explanation of a complex topic, they paper over conceptual cracks with smooth handwaving. Some people are not paying attention so they feel like they understood. Others are left with a feeling of frustration they cannot put their finger on. I think that’s our guy here.

    Thanks for the amazing video explaining Grover's Algorithm! It helped me intuitively understand what the algorithm is trying to do. P.s. there is a small error in 3:00 where the U_s operator should be I - 2|s><s| instead of I - |s><s|, which was correctly shown around 11:13 during the example.
