While the terms "redundancy" and "consensus" are often used as synonyms inthe context of quantum objectivity, we show here that these should beunderstood as two related but distinct notions, that quantify differentfeatures of the quantum-to-classical transition. We show that the two mainframeworks used to measure quantum objectivity, namely spectrum broadcaststructure and quantum Darwinism, are best suited to quantify redundancy andconsensus, respectively. Furthermore, by analyzing explicit examples of stateswith nonlocally encoded information, we highlight the potentially starkdifference between the degrees of redundancy and consensus. In particular, thiscauses a break in the hierarchical relations between spectrum broadcaststructure and quantum Darwinism. Our framework provides a new perspective tointerpret known and future results in the context of quantum objectivity,paving the way for a deeper understanding of the emergence of classicality fromthe quantum realm.
