    "abstract": "A misunderstanding that an arbitrary phase rotation of the marked state\ntogether with the inversion about average operation in Grover\u0027s search\nalgorithm can be used to construct a (less efficient) quantum search algorithm\nis cleared. The $\\pi$ rotation of the phase of the marked state is not only the\nchoice for efficiency, but also vital in Grover\u0027s quantum search algorithm. The\nresults also show that Grover\u0027s quantum search algorithm is robust.",
