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…
Convex geometry of Markovian Lindblad dynamics and witnessing non-Markovianity
Bihalan Bhattacharya, Samyadeb Bhattacharya
We develop a theory of linear witnesses for detecting non-Markovianity, based on the geometric structure of the set of Choi states for all Markovian evolutions having Lindblad type…
Convex resource theory of non-Markovianity
Samyadeb Bhattacharya, Bihalan Bhattacharya, A. S. Majumdar
We establish a convex resource theory of non-Markovianity under the constraint of small time intervals within the temporal evolution. We construct the free operations, free states…
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…
