Indefinite causal order enables perfect quantum communication with zero capacity channels
Giulio Chiribella, Manik Banik, Some Sankar Bhattacharya +6
Quantum mechanics is compatible with scenarios where the relative order between two events can be indefinite. Here we show that two independent instances of a noisy process can beh…
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…
Uncertainty principle as post-quantum nonlocality witness for continuous variable multi-mode scenario
Prathik J Cherian, Amit Mukherjee, Arup Roy +2
Uncertainty principle is one of the central concepts in quantum theory. Different forms of this particular principle have been discoursed in various foundational and information th…
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…
Analytical construction of non local operator for n-qubit Dicke state
Sutapa Saha, Some Sankar Bhattacharya, Arup Roy +2
Entanglement in multipartite quantum systems is much more elusive than its bipartite counterpart. In recent past the usefulness of multipartite entangled states in several informat…
