... In the quantum algorithm, what we want to do is to use the fact that there are an equal number of 0s and 1s, to get the 0s and 1s to cancel one another. First, however, we need to be clear as to what exactly is given in the quantum algorithm. The quantum algorithm does not oracle-query f , rather it ...
