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…
Stabilizing quantum simulations of lattice gauge theories by dissipation
Tobias Schmale, Hendrik Weimer
Simulations of lattice gauge theories on noisy quantum hardware inherently suffer from violations of the gauge symmetry due to coherent and incoherent errors of the underlying phys…
