Combinatorial structures in quantum correlation: A new perspective

Rohit kumar, Satyabrata Adhikari

Graph-theoretic structures play a central role in the description and analysis of quantum systems. In this work, we introduce a new class of quantum states, called -graph sta…

Construction of PPT entangled state and its detection by using second-order moment of the partial transposition

Rohit Kumar, Satyabrata Adhikari

We adopt a formalism by which we construct and detect a new family of positive partial transpose entangled states in dimensional system. Our detection method is ba…
