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…
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…
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…
