摘要: We introduce and analyze a one-dimensional quantum walk with two time-independent rotations on the coin. study influence property of due to second rotation Based asymptotic solution in long time limit, ballistic behaviour this is observed. This retains quadratic growth variance if combined operator coin unitary. That confirms no localization exhibits walk. result can be extended multiple
