Universal notion of classicality based on ontological framework

  title={Universal notion of classicality based on ontological framework},
  author={Shubhayan Sarkar},
Existence of physical reality in the classical world is a well-established fact from day-to-day observations. However within quantum theory, it is not straightforward to reach such a conclusion. A framework to analyse how observations can be described using some physical states of reality in a theory independent way was recently developed, known as ontological framework. Different principles when imposed on the ontological level give rise to different observations in physical experiments. Using…

Probing measurement problem of quantum theory with an operational approach

Exploiting the tension between the two dynamics of quantum theory (QT) or the so called "measurement problem" of QT within a modified version of Wigner’s Friend thought experiment, we point out that



Self-testing quantum systems of arbitrary local dimension with minimal number of measurements

This work proposes a self-testing protocol for the maximally entangled state of any local dimension using the minimum number of measurements possible, i.e., two per subsystem, and can be used to establish unbounded randomness expansion.
