The article titled “Quantum-to-the-Home: Achieving Gbits/s Secure Key Rates via Commercial Off-the-Shelf Telecommunication Equipment” [1] was found to contain materials from the following published article that was cited but not properly attributed [2]: “Z. Qu, I. B. Djordjevic, M. A. Neifeld, “RF-subcarrier-assisted Four-state Continuous-variable QKD Based on Coherent Detection,” Optics Letters, vol. 41, no. 23, pp. 5507-5510, 2016” [3]. The mathematical models and their description in appendices A and B in [1] were taken from [3] with some rewording of the text, and Figure 2 in [1] is similar to part of Figure 1 in [3].
