Two-parameter Family-Vicsek scaling in a dissipative XXZ spin chain
Cătălin Paşcu Moca, Doru Sticlet, Tamás Vicsek +1
Family-Vicsek (FV) scaling provides an understanding for the growth and finite-size saturation of fluctuations in classical systems. Here, we extend the FV roughness to transferred…
Skyrmionic qubits stabilized by Dzyaloshinskii-Moriya interaction as platforms for qubits and quantum gates
Doru Sticlet, Romulus Tetean, Coriolan Tiusan
Quantum computation departs from the classical paradigm of deterministic, bit-based processing by exploiting inherently quantum phenomena such as superposition and entanglement. We…
Non-stabilizerness as a Diagnostic of Criticality and Exceptional Points in Non-Hermitian Spin Chains
Cătălin Paşcu Moca, Doru Sticlet, Balázs Dóra
We investigate non-stabilizerness, also known as ``magic,'' to understand criticality and exceptional points in non-Hermitian quantum many-body systems. Our focus is on parity-time…
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…
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…
