Abstract: The relation between discrete Wigner function and quantum contextuality based on graph theory has been studied, following the work in [Nature 510,351(2014)]. To do this, non‐stabilizer projectors have been introduced to a series of non‐contextuality… read more here.

DOI: 10.1016/j.scib.2018.06.018
Abstract: Abstract Quantum nonlocality and quantum contextuality are the most curious properties that change our understanding of nature, and were observed independently in recent decades. One important question is whether both properties can be observed simultaneously.… read more here.

DOI: 10.1021/acsphotonics.7b00793
Abstract: In classical physics, properties of objects exist independently of the context, i.e., whether and how measurements are performed. Quantum physics showed this assumption to be wrong, and that Nature is indeed “contextual”. Contextuality has been… read more here.

DOI: 10.1038/s41598-019-53701-5
Abstract: An ontological model of an operational theory is considered to be universally noncontextual if both preparation and measurement noncontextuality assumptions are satisfied in that model. In this report, we first generalize the logical proofs of… read more here.

DOI: 10.1103/physrevlett.120.130401
Abstract: Simulating quantum contextuality with classical systems requires memory. A fundamental yet open question is what is the minimum memory needed and, therefore, the precise sense in which quantum systems outperform classical ones. Here, we make… read more here.

Quantum Contextuality and Indeterminacy

DOI: 10.3390/e22080867
Abstract: The circumstances of measurement have more direct significance in quantum than in classical physics, where they can be neglected for well-performed measurements. In quantum mechanics, the dispositions of the measuring apparatus-plus-environment of the system measured… read more here.
