A two-parameter entropy and its fundamental properties
Supriyo Dutta, Shigeru Furuichi, Partha Guha
This article proposes a new two-parameter generalized entropy, which can be reduced to the Tsallis and the Shannon entropy for specific values of its parameters. We develop a numbe…
Ihara Zeta Entropy
Supriyo Dutta, Partha Guha
In this article, we introduce an entropy based on the formal power series expansion of the Ihara Zeta function. We find a number of inequalities based on the values of the Ihara ze…
From Sharma-Mittal to von-Neumann Entropy of a Graph
Souma Mazumdar, Amrik Singh, Supriyo Dutta +2
In this article, we introduce the Sharma-Mittal entropy of a graph, which is a generalization of the existing idea of the von-Neumann entropy. The well-known R{é}nyi, Thallis, and…
Facets of quantum information under non-Markovian evolution
Javid Naikoo, Supriyo Dutta, Subhashish Banerjee
We consider two non-Markovian models: Random Telegraph Noise (RTN) and non-Markovian dephasing (NMD). The memory in these models is studied from the perspective of quantum Fisher i…
