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…
