TL;DR
This paper introduces Bell-type inequalities that are violated by all quantum states, providing a basis for experimental tests of state-independent quantum contextuality.
Contribution
It presents new Bell-type inequalities applicable to any quantum state, enabling experimental verification of quantum contextuality independent of the system's state.
Findings
Bell-type inequalities violated by all quantum states
An experimentally suitable inequality for testing state-independent contextuality
Supports the fundamental nonclassical nature of quantum mechanics
Abstract
We show that there are Bell-type inequalities for noncontextual theories that are violated by any quantum state. One of these inequalities between the correlations of compatible measurements is particularly suitable for testing this state-independent violation in an experiment.
