© 2021 Optical Society of America
In the funding section of [1], “Key Research and Development Program of Guangdong Province (2020B0303040001)” should be replaced by “Key-Area Research and Development Program of Guangdong Province (2020B0303040001),” and “Fundamental Research Funds for the Central Universities” should be replaced by “Fundamental Research Funds for the Central Universities (020414380141).”
In addition, the last sentence of the first paragraph on column 2, page 1 of the Letter [1] should be modified into: “...we propose a different heralded scheme utilizing single-photon-type interference [27–32,42,43], which was first proposed in the twin-field QKD [42].” The two new references ([42,43]) are [2,3] in this Erratum, respectively.
