A characterization of orthogonal permutative matrices of order 4
Amrita Mandal, Bibhas Adhikari
Orthogonal matrices which are linear combinations of permutation matrices have attracted enormous attention in quantum information and computation. In this paper, we provide a comp…
Limit theorems and localization of three state quantum walks on a line defined by generalized Grover coins
Amrita Mandal, Rohit Sarma Sarkar, Shantanav Chakraborty +1
In this article, we undertake a detailed study of the limiting behavior of a three-state discrete-time quantum walk on one dimensional lattice with generalized Grover coins. Two li…
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…
Periodicity of lively quantum walks on cycles with generalized Grover coin
Rohit Sarma Sarkar, Amrita Mandal, Bibhas Adhikari
In this paper we extend the study of three state lively quantum walks on cycles by considering the coin operator as a linear sum of permutation matrices, which is a generalization…
