Great video, would love if you were able to do an example video on factoring a small number using order finding, phase estimation etc. Struggling a bit with it.
At 10:20, how can you get the exponential function after the unitary operator acting on the vector j times? !0:51, why we have to consider the case j=k, they are not inner product, not about orthogonality.
from 8:58 to 9:06, I don't understand the case the summation is qual to 1) r if k=0, 2) otherwise 3) =0 if k is not equal to 0, can you give more explanation?
@@QuantumGyan Oh, now I see it, but only for a special case (e.g. r=8). It's hard for me to derive it for a general case, without using a special case. Anyway, thank you for your help and your work. :)
it was helpful thank you :)

Very helpful. Thank you very much!
Thanks it was helpful
At 5:03, should it be the summation times the exponent e times the "alpha k+1" with the eigenvector?

Very helpful video. Just one question: how did you come up with 5:05 ?
@@QuantumGyan Yes, it makes sense! Just expand the two summations and inspect them. Thank you very much!!! :)
@@QuantumGyan I cannot connect this with 4:52. Can you give this explicit or in more detailed way, please?

I know that there is math going on, and I can't prove it but I'm sure there is also some meth going on.
Viet?
