TL;DR
This paper presents an experimental validation of a nonclassicality test for a single qubit, analyzing its applicability to local realistic theories and demonstrating its practical implementation.
Contribution
It provides the first experimental realization of a nonclassicality test for a single particle based on a previously proposed theoretical framework.
Findings
The test distinguishes quantum from classical behavior in single qubits.
Experimental results support the nonclassical nature of single-particle states.
The study clarifies the scope of local realistic theories in quantum mechanics.
Abstract
In a recent paper [R. Alicki and N. Van Ryn, J. Phys. A: Math. Theor., 41, 062001 (2008)] a test of nonclassicality for a single qubit was proposed. Here, we discuss the class of local realistic theories to which this test applies and present an experimental realization.
