... Finally, state |Ψm i is observed, yielding some value i. The algorithm succeeds if and only if T [i] = x. In his paper, √ Grover proves that there exists a number m less than 2N such that the probability of success after m iterations is at least 1/2. This is correct, but one must be careful in using ...
