How Quantum Contextuality disappears in the Classical Limit
Arthur C. R. Dutra, Roberto D. Baldijão, Marcelo Terra Cunha
The emergence of classicality is fundamentally driven by the interaction between a quantum system and its environment. Foundational open-system approaches, notably the Caldeira-Leg…
Structure of quantum measurements implementable with one round of classical communication
Arthur C. R. Dutra, Ties-A. Ohst, Hai-Chau Nguyen +1
Measurements that can be implemented via local operations and classical communication (LOCC) constitute a class of operations that is available in future quantum networks in which…
Cartan-Khaneja-Glaser decomposition of via involutive automorphisms
John A. Mora Rodríguez, Arthur C. R. Dutra, Henrique N. Sá Earp +1
We present a novel algorithm for performing the Cartan-Khaneja-Glaser decomposition of unitary matrices in , a critical task for efficient quantum circuit design. Building…
Can multiple observers detect KS-contextuality?
Arthur C. R. Dutra, Roberto D. Baldijão, Marcelo Terra Cunha
KS-contextuality is a crucial feature of quantum theory. Previous research demonstrated the vanishing of -cycle KS-contextuality in setups where multiple independent observers m…
