Tuning the universality class of a quantum process by Trotterization
Robin Prampain dit Boulan, Jerom Jebai, Hendrik Weimer
The authors numerically study a discretized quantum contact process and show that the choice of Trotterization can shift the system’s universality class from a quantum one to the c…
Self-correction phase transition in the dissipative toric code
Sanjeev Kumar, Hendrik Weimer
We analyze a time-continuous version of a cellular automaton decoder for the toric code in the form of a Lindblad master equation. In this setting, a self-correcting quantum memory…
Dynamical quantum phase transition with divergent multipartite entanglement
Jie Chen, Ricardo Costa de Almeida, Hendrik Weimer
We investigate the nonequilibrium quench dynamics of the one-dimensional transverse-field Ising model in both integrable and nonintegrable regimes. In particular, we report on a no…
Efficient computation of topological order
Louis Fraatz, Amit Jamadagni, Hendrik Weimer
We analyze the computational aspects of detecting topological order in a quantum many-body system. We contrast the widely used topological entanglement entropy with a recently intr…
