Fig. 3: Averaged logarithmic negativity \(\langle {{{{{{\boldsymbol{ {\mathcal E}}}}} }}}_{{{{{{{\boldsymbol{A}}}}}}}_{1}:{{{{{{\boldsymbol{A}}}}}}}_{2}}\rangle\).

The error bars represent standard error of the mean over circuit instances. a Fix \({N}_{{A}_{1}}=2\) and \({N}_{{A}_{2}}=4\), then decrease \({N}_{B}\) from 9 to 1. b Fix \({N}_{B}=\) 3 or 0 and increase \({N}_{{A}_{1}}\) from 0 to 6. When \({N}_{B}=0\), the negativity approximately obeys volume law. In contrast, the negativity is saturated from \({N}_{{A}_{1}}=2\) to 4 when \({N}_{B}=3\).
