On the Origin of Beyond-Classical Advantage in the Parity-Permutation Problem
Jayashree Karmakar, Biswadeep Chatterjee, Rafiuddin Gazi +6
We investigate the task of identifying the parity (odd vs even) of an unknown permutation applied to particles. Classically, using fewer than distinct labels per particle l…
Emergence and Recovery of (logical) Kochen-Specker Contextuality via Hamilton Extension
Jayashree Karmakar, Biswadeep Chatterjee, Rafiuddin Gazi +5
The paper introduces a constructive method called the Hamilton extension that can turn Kochen‑Specker‑colorable vector sets into uncolorable ones, thereby generating logical KS con…
Local state antimarking : Nonlocality without entanglement
Biswadeep Chatterjee, Tathagata Gupta, Pratik Ghosal +1
A set of quantum states is said to be antidistinguishable if, upon being given a randomly chosen state, it is possible to identify a state that the system was definitively not prep…
