Ancilla-mediated fixed-point quantum search using Grover iterations
Grover's quantum search algorithm provides a fundamental quadratic speedup for unstructured datasets, reducing query complexity from $\mathcal{O}(N)$ to $\mathcal{O}(\sqrt{N})$. However, the algorithm's reliance on precise iteration counts leads to the ``souffl\'e problem,''where over-rotation results in a sharp declin...
