Implementation Scheme for Quantum Controlled Phase-Flip Gate Through Quantum Dot in Silicon Slow-Light Photonic Crystal Waveguide
Lam, Nghi Q.
We propose a scheme to realize controlled phase gate between two single photons through a single quantum dot in a slow-light photonic crystal waveguide. Enhanced Purcell factor and large β-factor lead to high gate fidelity over broadband frequencies compared to cavity-assisted system. The excellent physical integration of this photonic crystal waveguidesystem provides tremendous potential for large-scale quantum information processing.
