Facets of Non-locality and Advantage in Entanglement-Assisted Classical Communication Tasks
Sumit Rout, Anubhav Chaturvedi, Some Sankar Bhattacharya +1
We reveal key connections between non-locality and advantage in correlation-assisted classical communication. First, using the wire-cutting technique, we provide a Bell inequality…

Randomness-free Detection of Non-projective Measurements: Qubits & beyond
Sumit Rout, Some Sankar Bhattacharya, Paweł Horodecki
Non-projective measurements play a crucial role in various information-processing protocols. In this work, we propose an operational task to identify measurements that are neither…

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…
