Self-testing two-qubit maximally entangled states from generalized Clauser-Horne-Shimony-Holt tests
Self-testing two-qubit maximally entangled states from generalized Clauser-Horne-Shimony-Holt tests
Device-independent certification, also known as self-testing, aims at guaranteeing the proper functioning of untrusted and uncharacterized devices. For example, the quality of an unknown source expected to produce two-qubit maximally entangled states can be evaluated in a bi-partite scenario, each party using two binary measurements. The most robust approach consists …
