Hybrid Quantum Gates: High‐Fidelity Hybrid Quantum Gates between a Flying Photon and Diamond Nitrogen‐Vacancy Centers Assisted by Low‐ Q Single‐Sided Cavities (Ann. Phys. 1/2019)

In article number 1800312 , Ming Li, Jia‐Ying Lin, and Mei Zhang propose a high‐fidelity hybrid quantum Toffoli gate between a flying photon and diamond nitrogen‐vacancy centers assisted by low‐Q single‐sided cavities. Photon detectors are employed to herald errors that occur in the practical input‐output processes, which brings along the high fidelity while trading off a little efficiency.
