Thank you for the video. I am trying to learn quantum computing, but it has been difficult. As I learn more and starting to understand the concept, I started to realize, the difficulty of learning quantum computing certainly has to do with the difficult concept, but a lot has to do with the way it is taught. Therefore your way of shortening the length of the video and simplifying things has been very helpful. Appreciate it. I also checked on your full course. There seem to be some mistype here and there. Nothing to do with your knowledge of the concept, it just seem mistype that can easily be corrected. For example around 3:29 seconds of this video the second bit from the last bit having 2 pi i times 2 seem an error and it should just be 2 pi i since the (J1/2 + J2/4 ...) now reflects the multiplication of the 2. I am just started learning, so I could be wrong, but it seem to be a mistype. It will be good if you have mechanism to get feed back from the user in your full course so all the mistype can be corrected.
It seems like phase kickback fundamentally depends on there being a tensor product kind of thing, which I don’t recall states for separate systems being tensored for classical systems? I don’t think there is a classical version, but I could be wrong.
Thanks for the comment. Yes there is a classical version of phase estimation, it is eigenvalue estimation and there are many classical algorithms that do this (e.g. inverse power method). In terms of phase kickback this is uniquely a quantum mechanics concept so it is not part of regular classical computation.
I'm confused about something. The state j is an m qbit state while our state psi 4 is m+n qbits. It cannot be the fourrier transform of j. I think you forgot to remove the v

Thanks for the comment! Yes that 2 is a mistake I will pin your comment so people notice. Take Care!

Thanks for Watching!
Please we need simon' s algorithm and grover' s search algorithm as well 🙏🙏🙏🙏
Is there a classical version for the notion 1- of "phase estimation"? and 2 - of "phase kick back"? Thanks!
