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…
Genuinely entangled subspace with all-encompassing distillable entanglement across every bipartition
Sristy Agrawal, Saronath Halder, Manik Banik
In a multipartite scenario quantum entanglement manifests its most dramatic form when the state is genuinely entangled. Such a state is more beneficial for information theoretic ap…
Strong Quantum Nonlocality without Entanglement
Saronath Halder, Manik Banik, Sristy Agrawal +1
Quantum nonlocality is usually associated with entangled states by their violations of Bell-type inequalities. However, even unentangled systems, whose parts may have been prepared…
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…
Advantage of Quantum Theory Over Non-classical Models of Communication
Sutapa Saha, Some Sankar Bhattacharya, Tamal Guha +2
Quantum correlations provide dramatic advantage over the corresponding classical resources in several communication tasks. However a broad class of probabilistic theories exists th…
Family of bound entangled states on the boundary of Peres set
Saronath Halder, Manik Banik, Sibasish Ghosh
Bound entangled (BE) states are strange in nature: non-zero amount of free entanglement is required to create them but no free entanglement can be distilled from them under local o…
