Quantum scrambling of algebras of observables: the ${\mathbb{Z}}_2$-symmetric case

Paolo Zanardi, J. Karson Lewis

We consider unitary quantum scrambling for an entire class of observable algebras $\mathcal{A}$ whose commutant ${\mathcal{A}}^{\prime }=\mathbb{C}{\mathbb{Z}}_2$ is generated by a Hermitian in…
