Correction to: Nature https://doi.org/10.1038/s41586-020-03140-4 Published online 27 January 2021.

In the version of this article initially published, there was an error in Fig. 1. Due to an error in transcription of the data from Wang et al. (Phys. Rev. Lett. https://doi.org/10.1103/PhysRevLett.95.185701 (2005)), the melting curve showed incorrect pressure scaling. The original and revised figures are shown below. The curve has now been corrected in the HTML and PDF versions of the article.
