Every Little Thing Heat Does Is Magic
Rafael A. Macêdo, A. de Oliveira Junior, Naim E. Comar +4
How can one certify that an unknown quantum state possesses magic without resorting to full state tomography? We address this question by introducing two thermodynamic witnesses th…

Using spatiotemporal Born rule for testing macroscopic realism: some applications to the pseudo-density matrices and nonclassical temporal correlations
Naim Elias Comar, Lucas C. Céleri, Mia Stamatova +3
We show that, given an evolving quantum system and the quasiprobability distribution generated by the spatiotemporal generalization of the Born rule in pseudo density-matrices (PDM…

Contextuality in anomalous heat flow
Naim Elias Comar, Danilo Cius, Luis Felipe Santos +2
In classical thermodynamics, heat must spontaneously flow from hot to cold systems. In quantum thermodynamics, the same law applies when considering multipartite product thermal st…
