"All-versus-nothing" proof of genuine tripartite steering and entanglement certification in the two-sided device-independent scenario
Shashank Gupta, Debarshi Das, C. Jebarathinam +3
We consider the task of certification of genuine entanglement of tripartite states. For this purpose, we first present an "all-versus-nothing" proof of genuine tripartite Einstein-…
Detection of genuine tripartite entanglement by multiple sequential observers
Ananda G. Maity, Debarshi Das, Arkaprabha Ghosal +2
Due to the difficulties present in experimentally preparing genuine tripartite entanglement, it is important to explore the possibility of multiple usage of a single genuine entang…
The principle of information symmetry constrains the state-space in any physical theory
Manik Banik, Sutapa Saha, Tamal Guha +4
Symmetry shares an entwined history with the structure of physical theory. We propose a consequence of symmetry towards the axiomatic derivation of Hilbert space quantum theory. We…
Protecting quantum correlations in presence of generalised amplitude damping channel: the two-qubit case
Suchetana Goswami, Sibasish Ghosh, A. S. Majumdar
Any kind of quantum resource useful in different information processing tasks is vulnerable to several types of environmental noise. Here we study the behaviour of quantum correlat…
Thermodynamic utility of Non-Markovianity from the perspective of resource interconversion
Samyadeb Bhattacharya, Bihalan Bhattacharya, A. S. Majumdar
We establish a connection between non-Markovianity and negative entropy production rate for various classes of quantum operations. We analyse several aspects of unital and thermal…
Detecting non-Markovianity via uncertainty relations
Ananda G. Maity, Samyadeb Bhattacharya, A. S. Majumdar
We present a formalism for detection of non-Markovianity through uncertainty relations. We show that when there is an information back-flow to the system from its environment throu…
