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…
Quantum description of reality is epistemically incomplete
Anubhav Chaturvedi, Marcin Pawłowski, Debashis Saha
We ask whether the operational quantum description is complete at the level of preparations: can the empirically accessible properties of a finite preparation set be reproduced exa…
Robust certification of arbitrary outcome quantum measurements from temporal correlations
Debarshi Das, Ananda G. Maity, Debashis Saha +1
Certification of quantum devices received from unknown providers is a primary requirement before utilizing the devices for any information processing task. Here, we establish a pro…
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…
