Perfect State Transfer on Oriented Circulant Graphs: A Complete Classification
Xingkun Song
The continuous-time quantum walk on an oriented circulant graph is determined by the Fourier eigenvalues of its Hermitian adjacency matrix. We classify perfect state transfer (PST)…

Zero transfer on mixed graphs
Xingkun Song, Huiqiu Lin
In this paper, we investigate zero transfer on mixed graphs. Zero transfer is a quantum walk phenomenon in which the transition amplitude between two vertices is identically zero f…
