Synchronization of Two and Three Optoeletronic Oscillators Operating in Chaotic Regime: Numerical Simulations and Schemes for Secure Communication
G. L. de Oliveira, R. V. Ramos
In this work we show a strategy for synchronization of three optoelectronic oscillators (OEO) operating in chaotic regime. Two applications of synchronized OEOs in secure communica…

The Importance of the Algorithmic Information Theory to Construct a Possible Example Where NP#P
Rubens Viana Ramos
In this short communication, it is shown a simple problem using quantum circuits for which the algorithmic information theory guarantee that the minimal length of the algorithm abl…
