An Unbounded Separation of Almost-Quantum and Commuting-Operator Correlations in Zero-Error Communication
Rafiuddin Gazi, Biswadeep Chatterjee, Jayashree Karmakar +3
Almost-quantum correlations form the level of the Navascués--Pironio--Acín hierarchy. They strictly contain the quantum set, are characterized by a single semidefin…
Almost-Quantum Correlations Violate Information Causality
Anandamay Das Bhowmik, Manik Banik
Information causality (IC) posits that communicating m classical bits cannot give the receiver access to more than m bits of information about the sender's independent data. Althou…
All-vs-Nothing Operational Manifestation of Preparation Contextuality
Jayashree Karmakar, Rafiuddin Gazi, Biswadeep Chatterjee +4
Preparation contextuality is often manifested operationally through a quantitative advantage over preparation-noncontextual models in information-processing tasks, yet quantum theo…
Antidistinguishability of states in General Probabilistic Theories
Satyaki Manna, Anandamay Das Bhowmik
We investigate antidistinguishability of states within the framework of general probabilistic theories (GPTs). We formulate antidistinguishability, strong and equal antidistinguish…
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…
Bell Nonlocality and the Reality of Quantum Wavefunction
Anandamay Das Bhowmik, Preeti Parashar, Manik Banik
Status of quantum wavefunction is one of the most debated issues in quantum foundations -- whether it corresponds directly to the reality or just represents knowledge or informatio…
