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…
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…
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…
