Nonstabilizerness in open XXZ spin chains: Universal scaling and dynamics
Doru Sticlet, Balázs Dóra, Dominik Szombathy +2
Magic, or nonstabilizerness, is a crucial quantum resource, yet its dynamics in open quantum systems remain largely unexplored. We investigate magic in the open XXZ spin chain unde…

Independent stabilizer Rényi entropy and entanglement fluctuations in random unitary circuits
Dominik Szombathy, Angelo Valli, Cătălin Paşcu Moca +2
We investigate numerically the joint distribution of magic () and entanglement () in -qubit Haar-random quantum states. The distribution as well as the marginal…

Spectral Properties Versus Magic Generation in -doped Random Clifford Circuits
Dominik Szombathy, Angelo Valli, Cătălin Paşcu Moca +4
We study the emergence of complexity in deep random -qubit -gate doped Clifford circuits, as reflected in their spectral properties and in magic generation, characterized by…
