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…
Local Quantum State Marking
Samrat Sen, Edwin Peter Lobo, Sahil Gopalkrishna Naik +8
We propose the task of local state marking (LSM), where some multipartite quantum states chosen randomly from a known set of states are distributed among spatially separated partie…
