We are focusing on diamond NV centers as devices to realize quantum repeaters for the construction of next-generation quantum networks. When quantum entanglement generation is performed between multiple nodes, schemes using photon interference have the problem that differences in photon frequency, phase, or timing of interference can cause fidelity degradation. On the other hand, we have confirmed that a method called the emission-absorption scheme is tolerant to these errors, which we report here.
