Round 1
Reviewer 1 Report
The authors propose a passive light source monitoring scheme for twin-field quantum key distribution. They built a theoretical model and carried out numerical simulations with aim to employ the sending-or-not-sending protocol when there existing intensity fluctuations in the light sources, showing better performance than the reported active light source monitoring. I think the results of this manuscript can be published after the authors give clearer description of the method used in the numerical simulations performed.
