Phase matching in quantum searching
Gui Lu Long, Yan Song Li, Wei Lin Zhang +1
Each iteration in Grover's original quantum search algorithm contains 4 steps: two Hadamard-Walsh transformations and two amplitudes inversions. When the inversion of the marked st…

Arbitrary phase rotation of the marked state can not be used for Grover's quantum search algorithm
Gui Lu Long, Wei Lin Zhang, Yan Song Li +1
A misunderstanding that an arbitrary phase rotation of the marked state together with the inversion about average operation in Grover's search algorithm can be used to construct a…
