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,…
Bell Non-Locality in Many Body Quantum Systems with Exponential Decay of Correlations
Carlos H. S. Vieira, Cristhiano Duarte, Raphael C. Drumond +1
Using Bell-inequalities as a tool to explore non-classical physical behaviours, in this paper we analyze what one can expect to find in many-body quantum physics. Concretely, frami…
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…
