Characterizing qubit channels in the context of quantum teleportation
Arkaprabha Ghosal, Debarshi Das, Subhashish Banerjee
We consider a scenario where a party, say, Alice prepares a pure two-qubit (either maximally entangled or non-maximally entangled) state and sends one half of this state to another…
Information-disturbance trade-off in generalized entanglement swapping
Pratapaditya Bej, Arkaprabha Ghosal, Debarshi Das +2
We study information-disturbance trade-off in generalized entanglement swapping protocols wherein starting from Bell pairs and , one performs a…
Rating the performance of noisy teleportation using fluctuations in fidelity
Saptarshi Roy, Arkaprabha Ghosal
Quantum teleportation is one of the most pioneering features of the quantum world. Typically, the quality of a teleportation protocol is solely judged by its average fidelity. In t…
Optimal two-qubit states for quantum teleportation vis-à-vis state properties
Arkaprabha Ghosal, Debarshi Das, Saptarshi Roy +1
Quantum teleportation with a two-qubit state can be suitably characterized in terms of maximal fidelity and fidelity deviation, where the former is the maximal value of the average…
Detection of genuine tripartite entanglement by multiple sequential observers
Ananda G. Maity, Debarshi Das, Arkaprabha Ghosal +2
Due to the difficulties present in experimentally preparing genuine tripartite entanglement, it is important to explore the possibility of multiple usage of a single genuine entang…
Fidelity deviation in quantum teleportation with a two-qubit state
Arkaprabha Ghosal, Debarshi Das, Saptarshi Roy +1
Quantum teleportation with an arbitrary two-qubit state can be appropriately characterized in terms of maximal fidelity and fidelity deviation. The former quantifies optimality of…
