| Resumo | |
Quantum Darwinism proposes that the proliferation of redundant information plays a major role in the emergence of objectivity out of the quantum world. Is this kind of objectivity necessarily classical? We show that if one takes Spekkens's notion of noncontextuality as the notion of classicality and the approach of Brandao, Piani, and Horodecki to quantum Darwinism, the answer to the above question is ``'yes,{''} if the environment encodes the proliferated information sufficiently well. Moreover, we propose a threshold on this encoding, above which one can unambiguously say that classical objectivity has emerged under quantum Darwinism. (AU) | |
