Self-testing of multipartite GHZ states of arbitrary local dimension with arbitrary number of measurements per party
Shubhayan Sarkar, Remigiusz Augusiak
Device independent certification schemes have gained a lot of interest lately, not only for their applications in quantum information tasks but also their implications towards foun…
Self-testing of any pure entangled state with minimal number of measurements and optimal randomness certification in one-sided device-independent scenario
Shubhayan Sarkar, Jakub J. Borkała, Chellasamy Jebarathinam +3
Certification of quantum systems and their properties has become a field of intensive studies. Here, taking advantage of the one-sided device-independent scenario (known also as qu…
Demonstration of quantum correlations that are incompatible with absoluteness of measurement
Shubhayan Sarkar, Debashis Saha
Exploiting the tension between the two dynamics of quantum theory (QT) in the Wigner's Friend thought experiment, we point out that the standard QT leads to inconsistency in observ…
Certification of incompatible measurements using quantum steering
Shubhayan Sarkar, Debashis Saha, Remigiusz Augusiak
In this letter we consider the problem of certification of quantum measurements with an arbitrary number of outcomes. We propose a simple scheme for certifying any set of -outco…
An operational notion of classicality based on physical principles
Shubhayan Sarkar
One of the basic observations of the classical world is that physical entities are real and can be distinguished from each other. However, within quantum theory, the idea of physic…
