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…
Distillation of genuine tripartite Einstein-Podolsky-Rosen steering
Shashank Gupta, Debarshi Das, A. S. Majumdar
We show that a perfectly genuine tripartite EPR steerable assemblage can be distilled from partially genuine tripartite EPR steerable assemblages. In particular, we consider two ty…
Genuine Einstein-Podolsky-Rosen steering of three-qubit states by multiple sequential observers
Shashank Gupta, Ananda G. Maity, Debarshi Das +2
We investigate the possibility of multiple use of a single copy of three-qubit states for genuine tripartite Einstein-Podolsky-Rosen (EPR) steering. A pure three-qubit state of eit…
Experimental demonstration of one-sided device-independent self-testing of any pure two-qubit entangled state
Zhihao Bian, A. S. Majumdar, C. Jebaratnam +5
We demonstrate one-sided device-independent self-testing of any pure entangled two-qubit state based on a fine-grained steering inequality. The maximum violation of a fine-grained…
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…
