Hi,
I think I found a few typos, please review them.

  1. H3 / Theory / The quantum description: “…to replace S_z it with…"
  2. H3 / Theory / Appendix - The Matrix Exponential: “We we need to…”
  3. H3 / Codercise H.3.1d: “So, we’ve seen how to take something physical, turns its evolution into a mathematical expression, and then to do the same thing on a quantum computer!”
  4. I4 / Theory / Pauli X: “…can be still be used…”

Thank you!
