Emergence and Recovery of (logical) Kochen-Specker Contextuality via Hamilton Extension
Jayashree Karmakar, Biswadeep Chatterjee, Rafiuddin Gazi +5
Logical Kochen-Specker (KS) contextuality is widely regarded as an intrinsic property of specially constructed measurement configurations. We show instead that it can emerge from K…
Conclusive Identification Via Noisy Classical Channel: Superactivation and Quantum Advantage
Anushko Chattopadhyay, Ambuj, Rakesh Das +4
We introduce conclusive identification task for classical channels: a receiver identifies transmitted inputs without error when possible, and responds inconclusively when outputs a…
Locally unidentifiable subset of quantum states and its resourcefulness in secret password distribution
Pratik Ghosal, Arkaprabha Ghosal, Subhendu B. Ghosh +1
We introduce a hitherto unexplored form of quantum nonlocality, termed local subset unidentifiability, that arises from the limitation of spatially separated parties to perfectly i…
Genuine Activation of Quantum Nonlocality: Stronger Than Local Indistinguishability
Tathagata Gupta, Subhendu B. Ghosh, Ardra A +5
The structure of quantum theory assures the discrimination of any possible orthogonal set of states. However, the scenario becomes highly nontrivial in the limited measurement sett…
Activating Strongest Possible Nonlocality from Local Sets: An Elimination Paradigm
Subhendu B. Ghosh, Tathagata Gupta, Ardra A. V. +4
Apart from the Bell nonlocality, which deals with the correlations generated from the local input-output statistics, quantum theory exhibits another kind of nonlocality that involv…
Operational Characterization of Multipartite Nonlocal Correlations
Sagnik Dutta, Amit Mukherjee, Manik Banik
Nonlocality, one of the most puzzling features of multipartite quantum correlation, has been identified as a useful resource for device-independent quantum information processing.…
