Operational foundations of complementarity and uncertainty relations
Debashis Saha, Michał Oszmaniec, Łukasz Czekaj +2
The so-called preparation uncertainty can be understood in purely operational terms. Namely, it occurs when for some pair of observables, there is no preparation, for which they bo…
Device independent witness of arbitrary dimensional quantum systems employing binary outcome measurements
Mikołaj Czechlewski, Debashis Saha, Armin Tavakoli +1
Device independent dimension witnesses (DW) are a remarkable way to test the dimension of a quantum system in a prepare-and-measure scenario imposing minimal assumptions on the int…
Preparation contextuality as an essential feature underlying quantum communication advantage
Debashis Saha, Anubhav Chaturvedi
The study of ontology (hidden variables) provides for a vital ground on which significant non-classical features of quantum theory are revealed. One such non-classical ontic-featur…
