Pretty good state transfer in Grover walks on abelian Cayley graphs

Koushik Bhakta, Bikash Bhattacharjya

In this paper, we study pretty good state transfer (PGST) in Grover walks on graphs. We consider transfer of quantum states that are localized at the vertices of a graph and we use…

Perfect state transfer in Grover walks on association schemes and distance-regular graphs

Koushik Bhakta, Bikash Bhattacharjya

This paper investigates perfect state transfer in Grover walks, a model of discrete-time quantum walks. We establish a necessary and sufficient condition for the occurrence of perf…

On Hamiltonicity and Perfect Codes in Non-Cyclic Graphs of Finite Groups

Parveen Parveen, Bikash Bhattacharjya

Let \( G \) be a finite non-cyclic group. Define \( \mathrm{Cyc}(G) \) as the set of all elements \( a \in G \) such that for any , the subgroup \( \langle a, b \rangle \)…
