Superunsteerability as a quantifiable resource for random access codes assisted by Bell-diagonal states
C. Jebarathinam, Debarshi Das, Som Kanjilal +4
We show how nonclassical correlations in local bipartite states can act as a resource for quantum information processing. Considering the task of quantum random access codes (RAC)…
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…
Persistence of quantum violation of macrorealism for large spins even under coarsening of measurement times
Sumit Mukherjee, Anik Rudra, Debarshi Das +2
We investigate quantum violation of macrorealism for multilevel spin systems under the condition of coarsening of measurement times -- i.e., when measurement times have experimenta…
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…
Environmental effects on nonlocal correlations
Tamal Guha, Bihalan Bhattacharya, Debarshi Das +6
Environmental interactions are ubiquitous in practical instances of any quantum information processing protocol. The interaction results in depletion of various quantum resources a…
