Correction to: Nature Photonics, published online 1 July 2019.

In the version of this Article originally published online, the given volume number, article number and year in ref. 13 were incorrect; the full reference should have read ‘Giorgianni, F. et al. Leggett mode controlled by light pulses. Nat. Phys. 15, 341–346 (2019).’ This has now been corrected in all versions.
