Two-qubit mixed states and teleportation fidelity: Purity, concurrence, and beyond
Sumit Nandi, Chandan Datta, Arpan Das +1
To explore the properties of a two-qubit mixed state, we consider quantum teleportation. The fidelity of a teleported state depends on the resource state purity and entanglement, a…

Can Quantum discord increase in a quantum communication task?
Shubhayan Sarkar, Chandan Datta
Quantum teleportation of an unknown quantum state is one of the few communication tasks which has no classical counterpart. Usually the aim of teleportation is to send an unknown q…

Authentication protocol based on collective quantum steering
Debasis Mondal, Chandan Datta, Jaskaran Singh +1
It is well known that certain quantum correlations like quantum steering exhibit a monogamous relationship. In this paper, we exploit the asymmetric nature of quantum steering and…
