A constructive method for simulating small-scale quantum circuits by use of linear optical devices is presented. It relies on the representation of several quantum bits by a single photon, and on the implementation of universal quantum gates using simple optical components ~beam splitters, phase shifters, etc.!. This suggests that the optical realization of small quantum networks with present-d...

This paper will review some potential applications of optical logic devices. It will focus on a system that is based on perfect shuffle optical interconnects.

In this paper, a photonic crystal structure for comparing two bits has beenproposed. This structure includes four resonant rings and some nonlinear rods. Thenonlinear rods used inside the resonant rings were made of a doped glass whose linearand nonlinear refractive indices are 1.4 and 10-14 m2/W, respectively. Using Kerr effect,optical waves are guided toward the correc...

In this paper, we present a handwritten character recognition (HCR) system that aims to recognize first-order logic formulas and create editable text files of the recognized formulas. Dense feedforward neural networks (NNs) are utilized, their performance is examined under various training conditions methods. More specifically, after three algorithms (backpropagation, resilient propagation stoc...
