Quantum state transfer on a scalable network under unital and non-unital noise
Monika Rani, Subhashish Banerjee, Nikhil Swami +1
We investigate quantum state transfer on a class of bipartite graphs, namely the butterfly graphs, within the framework of discrete-time quantum walks. These graphs facilitate the…

Quantum state transfer and periodicity in discrete-time quantum walks under non--Markovian dephasing noise
Monika Rani, Supriyo Dutta, Subhashish Banerjee
In quantum communication, quantum state transfer from one location to another in a quantum network plays a prominent role, where the impact of noise could be crucial. The idea of s…

Non-Markovianity in Discrete-Time Open Quantum Random Walk on Arbitrary Graphs
Monika Rani, Supriyo Dutta, Subhashish Banerjee
In this work, we present a new model of the Discrete-Time Open Quantum Walk (DTOQW) applicable to an arbitrary graph, thereby going beyond the case of quantum walks on regular grap…
