quantum encryption questions

have two questions maybe you can help me with in quantum physics encryption.

1-Construct an OR-gate using CCN.

2-Show that the explicit matrix form of the Fredkin gate satisfies the logic
FT = {If A=0, then B’=B & C’=C} + {If A=1, then B’=C & C’ = B}.]

the book followed is
