On the origin of noisy states whose teleportation fidelity can be enhanced through dissipation
Somshubhro Bandyopadhyay
Recently Badziag \emph{et al.} \cite{badziag} obtained a class of noisy states whose teleportation fidelity can be enhanced by subjecting one of the qubits to dissipative interacti…

Teleportation and Secret Sharing with Pure Entangled States
Somshubhro Bandyopadhyay
We present two optimal methods of teleporting an unknown qubit using any pure entangled state. We also discuss how such methods can also have succesful application in quantum secre…
