Correction to: Nature Communications https://doi.org/10.1038/s41467-021-25006-7, published online 4 August 2021.

In the original version of this Article Equation 13 was mistakenly formulated as:

$${{{{{{\boldsymbol{\Omega }}}}}}}_{6}=\left(\begin{array}{lll}{\underline{\underline{0}}} & {\underline{\underline{0}}} & {{{{{{\boldsymbol{\Omega }}}}}}}_{2} \\ {{{{{{\boldsymbol{\Omega }}}}}}}_{2} & {\underline{\underline{0}}} & {\underline{\underline{0}}}\\ {\underline{\underline{0}}} & {{{{{{\boldsymbol{\Omega }}}}}}}_{2} & {{{{{{\boldsymbol{\Omega }}}}}}}_{2}\end{array}\right)$$

The correct formulation is:

$${{{{{{\boldsymbol{\Omega }}}}}}}_{6}=\left(\begin{array}{lll}{\underline{\underline{0}}} & {\underline{\underline{0}}} & {{{{{{\boldsymbol{\Omega }}}}}}}_{2}\\ {{{{{{\boldsymbol{\Omega }}}}}}}_{2} & {\underline{\underline{0}}} & {\underline{\underline{0}}}\\ {\underline{\underline{0}}} & {{{{{{\boldsymbol{\Omega }}}}}}}_{2} & {\underline{\underline{0}}}\end{array}\right)$$

This has been corrected in both the HTML and PDF versions of the Article.
