Abstract

A study was performed on the effect of unitary noise on Grover's quantum search algorithm. The noise resulted from tiny fluctuations and drift in the parameters of the components performing the computation. It was found that below the noise threshold, when the search fails, a state that differs from the marked state by only a few bits was provided.
