|---|---|---|
We propose two feasible schemes for realizing hybrid Toffoli gates with dipole-induced transparency (DIT) effect in series and parallel cavity-waveguide systems. The gate operations are accomplished by encoding information on flying photon and dipole emitter evanescently coupled to the microcavity, and the spatial as well as polarization states of photon will be flipped conditional on the quantum states of dipole emitters. The schemes could be physically realized in one step and straightforwardly extended to realize the N-qubit Toffoli gate, which greatly simplifies the experimental implementation of Toffoli gate and promises a much higher fidelity compared to those based on elementary gate decomposition. Benefiting from DIT effect, the schemes can be achievable without requirement of strong coupling condition of cavity-waveguide system, and they are insensitive to experimental noises, imperfections and the phase delay of adjacent microcavities, which may be feasible with present accessible technology. |
