A novel SO(3) picture for quantum searching
Gui Lu Long, Chang Cun Tu, Yan Song Li +2
An SO(3) picture of the generalized Grover's quantum searching algorithm,with arbitrary unitary transformation and with arbitrary phase rotations, is constructed. In this picture,…

An intrinsic limitation on the size of quantum database
Gui Lu Long, Yan Song Li, Wei Lin Zhang +1
It is found that Grover's quantum search algorithm is not robust against phase inversion and Hadmard transformation inaccuracies. Imperfect phase inversions and Hadmard-Walsh trans…
