Fundamental Circuit Pattern for Searching
Although the circuit in the previous section eliminated non-tagged quantum states, it can’t directly be used to search for solutions for your applications for the following reasons:
-
The qubits aren’t handled symmetrically: the control qubit of the CNOT gate is
and its
target is 
.
So for a problem in which the optimal solution isn’t
known beforehand, it’s tricky knowing how to place gates
so that the optimal solution is properly tagged.
-
The circuit to tag a state assumed you knew which state to tag. ...
