Nonstabilizerness generation in a multiparticle quantum walk
Cătălin Paşcu Moca, Doru Sticlet, Balázs Dóra +3
We investigate the generation of non-stabilizerness, or magic, in a multi-particle quantum walk by analyzing the time evolution of the stabilizer Rényi entropy . Our study con…
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…
Momentum space magic for the transverse field quantum Ising model
Balázs Dóra, Cătălin Paşcu Moca
Stabilizer entropies and quantum magic have been extensively explored in real-space formulations of quantum systems within the framework of resource theory. However, interesting an…
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…
Multiparticle quantum walk: a dynamical probe of topological many-body excitations
Bogdan Ostahie, Doru Sticlet, Cătălin Paşcu Moca +4
Recent experiments demonstrated that single-particle quantum walks can reveal the topological properties of single-particle states. Here, we generalize this picture to the many-bod…
