+We are now in superposition between all classical possibilities on the top wire
+and in $\ket{-}$ on the bottom wire.
+
+
+Next we apply the unitary $U_f$ on both wires.
+The Unitary is defined as:
+$U_f \ket{x,y} = \ket{x,y \otimes f(x)}$ 
+This unitary applies the function f to the bottom wire y.
+It can be calculated as follows:
