\section*{--------Pre-Production Review--------}

Do not use "et al." in your references. Revise your references to include the full author listings.

Ans: We have made the appropriate changes to Refs. [7,9]. We have also taken the opportunity to update Ref. [12] to the latest reference.

\section*{Summary of changes}
Ref. [7]: changed: F. Hou, R. Quan, R. Dong, X. Xiang, B. Li, T. Liu, X. Yang, H. Li, L. You, Z. Wang et al., “Fiber-optic two-way
quantum time transfer with frequency-entangled pulses,” Phys. Rev. A 100, 023849 (2019).

to: F. Hou, R. Quan, R. Dong, X. Xiang, B. Li, T. Liu, X. Yang, H. Li, L. You, Z. Wang, and S. Zhang, “Fiber-optic
two-way quantum time transfer with frequency-entangled pulses,” Phys. Rev. A 100, 023849 (2019).

Ref. [9]: changed: R. Quan, H. Hong, W. Xue, H. Quan, W. Zhao, X. Xiang, Y. Liu, M. Cao, T. Liu, S. Zhang et al., “Implementation
of field two-way quantum synchronization of distant clocks across a 7 km deployed fiber link,” arXiv preprint
arXiv:2109.00784 (2021).
