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…

Characterizing Optimal-speed unitary time evolution of pure and quasi-pure quantum states
John A. Mora Rodríguez, Brian Grajales, Marcelo Terra Cunha +1
We present a characterization of the Hamiltonians that generate optimal-speed unitary time evolution and the associated dynamical trajectory, where the initial states are either pu…

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…
