Sharma-Mittal Quantum Discord
Souma Mazumdar, Supriyo Dutta, Partha Guha
We demonstrate a generalization of quantum discord using a generalized definition of von-Neumann entropy, which is Sharma-Mittal entropy; and the new definition of discord is calle…
A Boolean Functions Theoretic Approach to Quantum Hypergraph States and Entanglement
Supriyo Dutta
The hypergraph states are pure multipartite quantum states corresponding to a hypergraph. It is an equal superposition of the states belonging to the computational basis. Given any…
Constructing Non-isomorphic Signless Laplacian Cospectral Graphs
Supriyo Dutta
In this article, we generate large families of non-isomorphic and signless Lalacian cospectral graphs using partial transpose on graphs. Our constructions are significantly powerfu…
Construction of cospectral graphs
Supriyo Dutta, Bibhas Adhikari
Construction of non-isomorphic cospectral graphs is a nontrivial problem in spectral graph theory specially for large graphs. In this paper, we establish that graph theoretical par…
