Analytical approach of using squeezed state formation of light for conducting all-optical noise free NAND logic operation

We report a new all-optical noise free NAND logic operation using squeezed state of light with high speed of operation. The squeezed state of light generated by means of optical parametric amplification (OPA). The lights were generated in the same way to maintain the same characteristics. Balance homodyne detection scheme is utilized to detect the squeezed state of light. It is one of the promising squeezed light based devices for the next generation logic optical circuits.
