Entanglement dynamics and phase transitions of the Floquet cluster spin chain
Alberto Verga
Abstract
One of the challenges in quantum information is to create quantum states that can be used as resources, for instance, in the measurement-based model of quantum computing. Here, the author investigates the generation, through a dynamical phase transition, of a topological entangled state, by the Floquet evolution of a chain of spins, whose ground state is the so-called cluster state, acted upon by a quantum walker. The nonergodic phase is characterized by the emergence of magnetic order, persistent at long times.
