-deformed --Rényi relative entropy
Srikrishna Maity, Shigeru Furuichi, Supriyo Dutta
In this article, we consider the -logarithm for defining three-parameter family of Rényi relative entropies that are generalization of the --Rényi relative entropies. A…
Perfect state transfer using Markovian quantum walk
Supriyo Dutta
The quantum Perfect State Transfer (PST) is a fundamental tool of quantum communication in a network. It is not easy to achieve in practice. The original idea of PST depends on 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…
Discrete-Time Open Quantum Walks for Vertex Ranking in Graphs
Supriyo Dutta
This article presents a new quantum PageRank algorithm on graphs using discrete-time open quantum walks. Google's PageRank is a widely used algorithm for ranking the web pages on t…
