Two numerical counterexamples contrary to the phase matching condition for quantum search
Wenliang Jin · viXra · 2013
In this short comment, by giving two numerical counterexamples directly contrary to the phase matching condition presented by Long \emph{et al.}, I show that Grover's conclusion that his algorithm can be extended to the case when the two phase inversions are replaced by arbitrary phases (Phys. Rev. Lett. {\bf 80}, 4329--4332, 1998) in a sense is correct.
