- Correction: Author Correction, published 21 August 2023, https://doi.org/10.1038/s41467-023-40866-x (Nat. Commun. 14:5059). Read in full (HTML and 1-page PDF, sha256 5018ada3…6a223).
- Scope (verbatim from the correction): the original Discussion section, 4th paragraph, 6th sentence, read:
- Lane A reading of significance (limited to what the text says): the correction replaces a proposed key-refresh mechanism (encrypting a fresh key R under C) with a different one (growing C with extra QKD states, authenticated by κ). It changes no equation, figure, table, measured value or security number. The article page's change history lists only this correction. The corrected sentence is present in the current HTML (checked).
- Impact on QMint: if QMint models multi-purchase use of the same client key C, it must follow the corrected mechanism, or treat unbounded purchases as out of model and use the n-time-secure MAC bound. The single-payment D1 game is unaffected.
