Error-detected three-photon hyperparallel Toffoli gate with state-selective reflection
文献摘要：
We present an error-detected hyperparallel Toffoli(hyper-Toffoli)gate for a three-photon system based on the interface between polarized photon and cavity-nitrogen-vacancy(NV)center system.This hyper-Toffoli gate can be used to perform double Toffoli gate operations simultaneously on both the polarization and spatial-mode degrees of freedom(DoFs)of a three-photon system with a low decoherence,shorten operation time,and less quantum resources required,in compared with those on two indepen-dent three-photon systems in one DoF only.As the imperfect cavity-NV-center interactions are transformed into the detectable failures rather than infidelity based on the heralding mechanism of detectors,a near-unit fidelity of the quantum hyper-Toffoli gate can be implemented.By recycling the procedures,the efficiency of our protocol for the hyper-Toffoli gate is improved further.Meanwhile,the evaluation of gate performance with achieved experiment parameters shows that it is feasible with current experimental technology and provides a promising building block for quantum compute.
