From: Universality in volume-law entanglement of scrambled pure quantum states
A schematic picture of our setup. The second Rényi Page curve for pure states, \(S_2(\ell )\), follows the volume law when \(\ell\) is small, but gradually deviates from it as \(\ell\) grows. At the middle, \(\ell {\mathrm{ = }}L{\mathrm{/}}2\), the maximal value is obtained, where the deviation from the volume law is ln 2 (see the Results section). Past the middle \(\ell {\mathrm{ = }}L{\mathrm{/}}2\), it decreases toward \(\ell {\mathrm{ = }}L\) and becomes symmetric under \(\ell \leftrightarrow L - \ell\)
