Topological phase transition in a symmetric blockade structure
Johannes Mögerle, Simon Fell, Tobias F. Maier +4
We present a numerical study of a blockade Hamiltonian with a local symmetry. For such models, the existence of a topologically ordered ground state has been proven…
Excitation gap of a blockade structure with topological order
Simon Fell, Tobias F. Maier, Hans Peter Büchler +1
Mathematically rigorous statements on the spectral gap of quantum many-body systems in the thermodynamic limit are notoriously difficult to prove -- yet they are of fundamental imp…
Robust detection of an entanglement transition in the projective transverse field Ising model
Felix Roser, Etienne M. Springer, Hans Peter Büchler +1
We propose a scalable and noise-resilient protocol for the detection of the entanglement transition in a projective version of the transverse field Ising model. Entanglement transi…
Quantum doubles in symmetric blockade structures
Hans Peter Büchler, Tobias F. Maier, Simon Fell +1
Exactly solvable models of topologically ordered phases with non-abelian anyons typically require complicated many-body interactions which do not naturally appear in nature. This m…
Topological order in symmetric blockade structures
Tobias F. Maier, Hans Peter Büchler, Nicolai Lang
The bottom-up design of strongly interacting quantum materials with prescribed ground state properties is a highly nontrivial task, especially if only simple constituents with real…
Decoding the Projective Transverse Field Ising Model
Felix Roser, Hans Peter Büchler, Nicolai Lang
The competition between non-commuting projective measurements in discrete quantum circuits can give rise to entanglement transitions. It separates a regime where initially stored q…
