+Another well known quantum algorithm for searching.
+Takes a function $f : \{0,1\}^n \rightarrow \{0,1\}$ where f(x) = 1 for exactly one x. 
+The goal is to find x.

+New gates: $V_f$ and FLIP$_*$

+$\ket{*}$ denotes the superposition over al classical possibilities.
+
+### Oracle $V_f$

+We use the Unitary $U_f$ as previously defined to construct $V_f$

+### FLIP$_*$
+
+We first need FLIP$_0$ defined as follows:

+This is implemented via this circuit:

+Z is a Pauli matrix and the empty circles denote negative control wires.
+So Z is only applied if all other wires are $\ket{0}$
