Fractional Revival and Association Schemes

Ada Chan, Gabriel Coutinho, Christino Tamon +2

Fractional revival occurs between two vertices in a graph if a continuous-time quantum walk unitarily maps the characteristic vector of one vertex to a superposition of the charact…

Perfect State Transfer on Weighted Graphs of the Johnson Scheme

Luc Vinet, Hanmeng Zhan

We characterize perfect state transfer on real-weighted graphs of the Johnson scheme $J (n, k)$ . Given $J (n, k) = {A_{1}, A_{2}, \dots, A_{k}}$ and $A(X) = w_0A_0 + \cd…

Perfect State Transfer in a Spin Chain without Mirror Symmetry

Gabriel Coutinho, Luc Vinet, Hanmeng Zhan +1

We introduce an analytical $X X$ spin chain with asymmetrical transport properties. It has an even number $N + 1$ of sites labeled by $n = 0, \dots N$ . It does not exhibit perfect state…
