Resumen:
We present here a classical optics device based on an imaging
architecture as an analogy of a quantum system where the violation of
the Bell inequality can be evidenced. Quantum states are encoded using
an electromagnetic wave modulated in amplitude and phase. Unitary
operations involved in the measurement of the observables are simulated
with the use of a coherent optical processor. The images obtained in the
output of the process contain all the information about the possible
outcomes of the joint measurement. By measuring the intensity
distribution in the image plane we evaluate the mean values of the
simulated observables. The obtained experimental results show how some
correlations of Clauser-Horne-Shimony-Holt-type exceed the upper bound
imposed by the local realism hypothesis as a consequence of the joint
effect of entanglement and two-particle interference.
