Independent density and coherence skin effects in adaptive fermion circuits
Karim Chahine, Markus Siegl, Michael Buchhold
Adaptive circuits use measurements and outcome-conditioned feedback to implement nonreciprocal dynamics without postselection. We show that fermion circuits host independently tuna…
Spectral Transitions of the Entanglement Hamiltonian in Monitored Free Fermions
Karim Chahine, Michael Buchhold
We numerically investigate measurement-induced phase transitions in monitored free fermions through the spectral and eigenstate properties of the entanglement Hamiltonian. By analy…
Entanglement dynamics in monitored Kitaev circuits: loop models, symmetry classification, and quantum Lifshitz scaling
Kai Klocke, Daniel Simm, Guo-Yi Zhu +2
Quantum circuits offer a versatile platform for simulating digital quantum dynamics and uncovering novel states of non-equilibrium quantum matter. One principal example are measure…
Robustness and measurement-induced percolation of the surface code
Thomas Botzung, Michael Buchhold, Sebastian Diehl +1
We examine the robustness of a logical qubit in the planar surface code subject to 'measurement-errors', i.e., to local Pauli measurements at known positions. This yields a measure…
