Facets of bipartite nonlocality sharing by multiple observers via sequential measurements
Debarshi Das, Arkaprabha Ghosal, Souradeep Sasmal +2
Recently, it has been shown that at most two observers (Bobs) can sequentially demonstrate bipartite nonlocality with a spatially separated single observer (Alice) invoking a scena…
Detecting Einstein-Podolsky-Rosen steering through entanglement detection
Debarshi Das, Souradeep Sasmal, Sovik Roy
Quantum inseparabilities can be classified into three inequivalent forms: entanglement, Einstein-Podolsky-Rosen (EPR) steering, and Bell's nonlocality. Bell-nonlocal states form a…
Sharing of tripartite nonlocality by multiple observers measuring sequentially at one side
Sutapa Saha, Debarshi Das, Souradeep Sasmal +4
Standard tripartite nonlocality and genuine tripartite nonlocality can be detected by the violations of Mermin inequality and Svetlichny inequality, respectively. Since tripartite…
Role of maximally entangled states in the context of linear steering inequalities
Debarshi Das, Souradeep Sasmal, Arup Roy
Linear steering inequalities are useful to check whether a bipartite state is steerable when both the parties are allowed to perform dichotomic measurements on their parts. In…
One-sided Device-independent Self-testing of any Pure Two-qubit Entangled State
Suchetana Goswami, Bihalan Bhattacharya, Debarshi Das +3
We consider the problem of -sided device-independent self-testing of any pure entangled two-qubit state based on steering inequalities which certify the presence of quantum stee…
