Localization of two-dimensional quantum walks defined by generalized Grover coins
Amrita Mandal, Rohit Sarma Sarkar, Bibhas Adhikari
Localization phenomena of quantum walks makes the propagation dynamics of a walker strikingly different from that corresponding to classical random walks. In this paper, we study t…
