Hello,
I think there is contradictions between the solutions of exercice 1 and 2 of homework 8 and between the course or maybe I am totally wrong :
1) Exercice 2:
bell states in course
bell states in the solution:
which are different and lead to different solutions
2)Exercice 1:
In the course we use Z for 10 state:
in the solution its iY which is XZ :
Thank you.
