One-half reflected entropy is not a lower bound for entanglement of purification

Josiah Couch, Phuc Nguyen, Sarah Racz +2

In recent work, Akers et al. proved that the entanglement of purification $E_{p} (A : B)$ is bounded below by half of the $q$ -Rényi reflected entropy $S_{R}^{(q)} (A : B)$ for all $q \geq 2$ ,…

Scrambling in quantum cellular automata

Brian Kent, Sarah Racz, Sanjit Shashi

Scrambling is the delocalization of quantum information over a many-body system and underlies all quantum-chaotic dynamics. We employ discrete quantum cellular automata as classica…
