Realizing quantum controlled phase-flip gate through quantum dot in silicon slow-light photonic crystal waveguide
arXiv:0803.1017 · doi:10.1063/1.2999588
Abstract
We propose a scheme to realize controlled phase gate between two single photons through a single quantum dot in slow-light silicon photonic crystal waveguide. Enhanced Purcell factor and beta factor lead to high gate fidelity over broadband frequencies compared to cavity-assisted system. The excellent physical integration of this silicon photonic crystal waveguide system provides tremendous potential for large-scale quantum information processing.
