Universality of Sudden Death of Entanglement
F. F. Fanchini, P. E. M. F. Mendonca, R. d. J. Napolitano
We present a constructive argument to demonstrate the universality of the sudden death of entanglement in the case of two non-interacting qubits, each of which generically coupled…
Alternative fidelity measure for quantum states
Paulo E. M. F. Mendonca, Reginaldo d. J. Napolitano, Marcelo A. Marchiolli +2
We propose an alternative fidelity measure (namely, a measure of the degree of similarity) between quantum states and benchmark it against a number of properties of the standard Uh…
Optimal tracking for pairs of qubit states
Paulo E. M. F. Mendonca, Alexei Gilchrist, Andrew C. Doherty
In classical control theory, tracking refers to the ability to perform measurements and feedback on a classical system in order to enforce some desired dynamics. In this paper we i…
