Periodicity of bipartite walk on biregular graphs with conditional spectra

Qiuting Chen

In this paper we study a class of discrete quantum walks, known as bipartite walks. These include the well-known Grover's walks. Any discrete quantum walk is given by the powers of…

Hamiltonians of Bipartite Walks

Qiuting Chen, Chris Godsil, Mariia Sobchuk +1

In this paper, we introduce a discrete quantum walk model called bipartite walks. Bipartite walks include many known discrete quantum walk models, like arc-reversal walks, vertex-f…

Pair State Transfer

Qiuting Chen, Chris Godsil

Let $L$ denote the Laplacian matrix of a graph $G$ . We study continuous quantum walks on $G$ defined by the transition matrix $U (t) = exp (i t L)$ . The initial state is of t…
