We describe a scalable nanocavity array, with single quantum dots, for universal single-operation N-qubit quantum gate. A single two-level system controls the lineshapes, departing from optical-analog of electromagnetically-induced-transparency, with high fidelity and low photon loss.
We fabricated photonic crystal nanocavities to enhance erbium (Er) emission in silicon rich nitride nanocrystals. We observed experimental quality factors of ~6000 and 20-fold enhancement, in agreement with numerical calculations of the Purcell effect.
An optical scattering theory is introduced that predicts significant disorder-induced resonance shifts in photonic-crystal nanocavities. Even for nm-scale imperfections, we calculate blue shifts of several meV, two orders of magnitude larger than the cavity linewidth.
A pulse delay corresponding to a slow group velocity of ~0.008 c was observed in a low-loss coupled cavity waveguide formed by 60 photonic crystal nanocavities whose intrinsic Q was as high as 106.
