Vindication of entanglement-based witnesses of non-classicality in hybrid systems
Emanuele Marconato,
Chiara Marletto
Abstract:Recently, Vedral and one of us proposed an entanglement-based witness of non-classicality in systems that need not obey quantum theory, based on constructor-information-theoretic ideas [1,3], which offers a robust foundation for recently proposed table-top tests of non-classicality in gravity, [2,3]. The witness asserts that if a mediator can entangle locally two quantum systems, then it has to be non-classical. Hall and Reginatto [4,5] claimed that there are classical systems that can entangle two quantum sys… Show more
