Correction to: Nature Photonics https://doi.org/10.1038/s41566-022-01023-w, published online 23 June 2022.

In the version of this article initially published, there was an error in the expression directly following equation (3) where the text now reading “where |v1〉=TB|u1〉 and |v2〉= TB|u2〉” appeared initially as “where |v1〉 =TB + t12|u2〉 and |v2〉 = TB.” The error has been corrected in the HTML and PDF versions of the article.
