Paper Abstract

Photon Logic gates based on quantum coherence have been presented for Boolean logic operations of NAND. The present photon logic gates use quantum coherence in a three-level system interacting with resonant Raman optical fields. In a specific condition of ultraslow light, the quantum coherence can be greatly enhanced so that ultralow power light can be used for photon switching applications. Unlike conventional optical switching methods, the photon switching is free from the population relaxation constraint but relies on quantum coherence (phase relaxation). By combing two photon switches in parallel, we performed Boolean logic gate operations.
