Multiparty orthogonal product states with minimal genuine nonlocality
Sumit Rout, Ananda G. Maity, Amit Mukherjee +2
Nonlocality without entanglement and its subsequent generalizations offer deep information-theoretic insights and subsequently find several useful applications. Concept of genuinel…
Nonlocality Without Entanglement: Quantum Theory and Beyond
Some Sankar Bhattacharya, Sutapa Saha, Tamal Guha +1
Quantum nonlocality without entanglement (Q-NWE) encapsulates nonlocal behavior of multipartite product states as they may entail global operation for optimal decoding of the class…
Genuinely Nonlocal Product Bases: Classification and Entanglement Assisted Discrimination
Sumit Rout, Ananda G. Maity, Amit Mukherjee +2
An orthogonal product basis of a composite Hilbert space is genuinely nonlocal if the basis states are locally indistinguishable across every bipartition. From an operational point…
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…
