A General Phase Matching Condition for Quantum Searching Algorithm
Che-Ming Li, Chi-Chuan Hwang, Jin-Yuan Hsieh, Kuo-Shong Wang
Abstract
A general consideration on the phase rotations in quantum searching algorithm is taken in this work. As four phase rotations on the initial state, the marked states, and the states orthogonal to them are taken account, we deduce a phase matching condition for a successful search. The optimal options for these phase are obtained consequently.
