Synchronous observation of Bell nonlocality and state-dependent Kochen-Specker contextuality
Lei Xiao, Gabriel Ruffolo, André Mazzari +4
Bell nonlocality and Kochen-Specker contextuality are two remarkable nonclassical features of quantum theory, related to strong correlations between outcomes of measurements perfor…
Emergence of noncontextuality under quantum Darwinism
Roberto D. Baldijão, Rafael Wagner, Cristhiano Duarte +2
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…
Investigating Coarse-Grainings and Emergent Quantum Dynamics with Four Mathematical Perspectives
Cristhiano Duarte, Barbara Amaral, Marcelo Terra Cunha +1
With the birth of quantum information science, many tools have been developed to deal with many-body quantum systems. Although a complete description of such systems is desirable,…
Measurement compatibility in Bell nonlocality tests
Tassius Temistocles, Rafael Rabelo, Marcelo Terra Cunha
Incompatibility of observables, or measurements, is one of the key features of quantum mechanics, related, among other concepts, to Heisenberg's uncertainty relations and Bell nonl…
Quantifying quantum invasiveness
Saulo V. Moreira, Marcelo Terra Cunha
We propose a resource theory of the quantum invasiveness of general quantum operations, i.e., those defined by quantum channels in Leggett-Garg scenarios. We are then able to compa…
Uniqueness of the joint measurement and the structure of the set of compatible quantum measurements
Leonardo Guerini, Marcelo Terra Cunha
We address the problem of characterising the compatible tuples of measurements that admit a unique joint measurement. We derive a uniqueness criterion based on the method of pertur…
