Some Directions beyond Traditional Quantum Secret Sharing
Sudhir Kumar Singh, R. Srikanth
We investigate two directions beyond the traditional quantum secret sharing (QSS). First, a restriction on QSS that comes from the no-cloning theorem is that any pair of authorized…
Assisted Quantum Secret Sharing
Sudhir Kumar Singh, R. Srikanth
A restriction on quantum secret sharing (QSS) that comes from the no-cloning theorem is that any pair of authorized sets in an access structure should overlap. From the viewpoint o…
A combinatorial approach for studying LOCC transformations of multipartite states
Sudhir Kumar Singh, Sudebkumar Prasant Pal, Somesh Kumar +1
We develop graph theoretic methods for analysing maximally entangled pure states distributed between a number of different parties. We introduce a technique called {\it bicolored m…
Combinatorial Approaches in Quantum Information Theory
Sudhir Kumar Singh
We investigate the exploitation of various combinatorial properties of graphs and set systems to study several issues in quantum information theory. We characterize the combinatori…
Generalized Quantum Secret Sharing
Sudhir Kumar Singh, R. Srikanth
We explore a generalization of quantum secret sharing (QSS) in which classical shares play a complementary role to quantum shares, exploring further consequences of an idea first s…
