Monogamy of quantum correlations in three qubit pure states using Rajagopal-Rendell (RR) quantum deficit
Sudha, A. R. Usha Devi, A. K. Rajagopal
The limitation on the shareability of quantum entanglement over several parties, the so-called monogamy of entanglement, is an issue that has caught considerable attention of quant…

Quantumness of correlations and entanglement
A. R. Usha Devi, A. K. Rajagopal, Sudha
Generalized measurement schemes on one part of bipartite states, which would leave the set of all separable states insensitive are explored here to understand quantumness of correl…

Majorana representation of symmetric multiqubit states
A. R. Usha Devi, Sudha, A. K. Rajagopal
As early as 1932, Majorana had proposed that a pure permutation symmetric state of N spin- 1 2 particles can be represented by N spinors, which correspond geometrically to N points…
