Security bounds for unidimensional discrete-modulated CV-QKD: a Gaussian extremality approach
John A. Mora Rodríguez, John A. Mora Rodriguez, Maron F. Anka +3
Unidimensional (1D) Gaussian-modulated continuous-variable quantum key distribution protocols have been proposed as a way to simplify implementation and reduce costs through single…

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…
