    "abstract": "Grover presented the phase-shift search by replacing the selective inversions\nby selective phase shifts of $\\pi /3$. In this paper, we investigate the\nphase-shift search with general equal phase shifts. We show that for small\nuncertainties, the failure probability of the Phase-$\\pi /3$ search is smaller\nthan the general phase-shift search and for large uncertainties, the success\nprobability of the large phase-shift search is larger than the Phase-$\\pi /3$\nsearch. Therefore, the large phase-shift search is suitable for large-size of\ndatabases.",
