Full Adder Based on Quantum Gate

We proposed a novel structure of ultrafast alloptical full adder based on the Cross-Phase Modulation (XPM) that is a principle nonlinear effect in a Semiconductor Optical Amplifier (SOA) assisted Mach- Zehnder Interferometer (MZI). In this architecture Alloptical logic gates including: Feynman, Toffoli and Peres gates are used to implement all optical full adder. By usingthe presented structure, we obtain low power penalty for designed full adder and error-free performance at 10Gb/s and the receiver sensitivity for a bit-error rate of 10−9 are below -10dBm. In additional, the results show this structure will enhance the future optical signal processing applicationfor ultrafast operation.
