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,…
Semidefinite tests for quantum network topologies
Johan Åberg, Ranieri Nery, Cristhiano Duarte +1
Quantum networks play a major role in long-distance communication, quantum cryptography, clock synchronization, and distributed quantum computing. Generally, these protocols involv…
Noncontextuality Inequalities from Antidistinguishability
Matthew S. Leifer, Cristhiano Duarte
Noncontextuality inequalities are usually derived from the distinguishability properties of quantum states, i.e. their orthogonality. Here, we show that antidistinguishability can…
Effective state as compatibility between agents
Cristhiano Duarte
Shedding a new light in the coarse-graining scenario, in this contribution we came up with different necessary and sufficient conditions for the existence of a well-defined coarse-…
Graph Approach to Extended Contextuality
Barbara Amaral, Cristhiano Duarte
Exploring the graph approach, we restate the extended definition of noncontextuality provided by the contextuality-by-default framework. This extended definition avoids the assumpt…
