Schemes to avoid entanglement sudden death of decohering two qubit system
Namitha C, S V M Satyanarayana
We investigate the entanglement dynamics of two interacting qubits in a common vacuum environment. The inevitable environment interaction leads to entanglement sudden death (ESD) i…

Rank dependent bounds on mixedness and entanglement for quantum teleportation
K. G Paulson, S. V. M Satyanarayana
Entanglement and mixedness of a bipartite mixed state resource are crucial for the success of quantum teleportation. Upper bounds on measures of mixedness, namely, von Neumann entr…
