Entanglement is not a lower bound for geometric discord
Swapan Rana, Preeti Parashar
We show that partial transposition of any state can have at most number of negative eigenvalues. This extends a decade old result of case by Sanpe…

Geometric discord and Measurement-induced nonlocality for well known bound entangled states
Swapan Rana, Preeti Parashar
We employ geometric discord and measurement induced nonlocality to quantify non classical correlations of some well-known bipartite bound entangled states, namely the two families…

Tight lower bound on geometric discord of bipartite states
Swapan Rana, Preeti Parashar
We use singular value decomposition to derive a tight lower bound for geometric discord of arbitrary bipartite states. In a single shot this also leads to an upper bound of measure…
