Characterization of the quantumness of unsteerable tripartite correlations
Debarshi Das, C. Jebaratnam, Bihalan Bhattacharya +3
Quantumness for a bipartite unsteerable quantum correlation is operationally characterized by the notion of super-unsteerability. Super-unsteerability refers to the requirement of…
Operational characterization of quantumness of unsteerable bipartite states
Debarshi Das, Bihalan Bhattacharya, Chandan Datta +4
Recently, the quantumness of local correlations arising from separable states in the context of a Bell scenario has been studied and linked with superlocality [Phys. Rev. A {\bf 95…
Tripartite entanglement detection through tripartite quantum steering in one-sided and two-sided device-independent scenarios
C. Jebaratnam, Debarshi Das, Arup Roy +5
In the present work, we study tripartite quantum steering of quantum correlations arising from two local dichotomic measurements on each side in the two types of partially device-i…
Cost of Einstein-Podolsky-Rosen steering in the context of extremal boxes
Debarshi Das, Shounak Datta, C. Jebaratnam +1
Einstein-Podolsky-Rosen steering is a form of quantum nonlocality which is weaker than Bell nonlocality, but stronger than entanglement. Here we present a method to check Einstein-…
Local marginals ameliorate device independent witnessing of genuine entanglement
Some Sankar Bhattacharya, Biswajit Paul, Arup Roy +3
We consider the problem of determining the presence of genuine multipartite entanglement through the violation of Mermin's Bell-type inequality (MI). Though the violation of MI can…
Operational nonclassicality of local multipartite correlations in the limited-dimensional simulation scenario
C. Jebaratnam, Debarshi Das, Suchetana Goswami +2
For a bipartite local quantum correlation, superlocality refers to the requirement for a larger dimension of the random variable in the classical simulation protocol than that of t…
