The discrete time quantum walk (DTQW) is defined as the quantum mechanical analogue of the random walk and tends to be one of the important tools on quantum information science, especially quantum speedup algorithm, quantum simulator, and quantum state transfer. We consider a new class of the DTQW, which is self-dual and has the inhomogeneous coin. We show the localization phenomena and the connection to the eigenvalue spectrum [1]. In this talk, I will show more details on our model.
