# Universal hyperparallel hybrid photonic quantum gates with dipole-induced transparency in the weak-coupling regime

@article{Ren2015UniversalHH, title={Universal hyperparallel hybrid photonic quantum gates with dipole-induced transparency in the weak-coupling regime}, author={Bao‐Cang Ren and Guan-Yu Wang and Fuguo Deng}, journal={Physical Review A}, year={2015}, volume={91}, pages={032328} }

We present the dipole induced transparency (DIT) of a diamond nitrogen-vacancy center embedded in a photonic crystal cavity coupled to two waveguides, and it is obvious with the robust and flexible reflectance and transmittance difference of circularly polarized lights between the uncoupled and the coupled cavities even in the bad cavity regime (the Purcell regime). With this DIT, we propose two universal hyperparallel hybrid photonic quantum logic gates, including a hybrid hyper-controlled-not…
