Universality in driven open quantum matter
Lukas M. Sieberer, Michael Buchhold, Jamir Marino +1
Universality is a powerful concept, which enables making qualitative and quantitative predictions in systems with extensively many degrees of freedom. It finds realizations in almo…
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…
Field theory for the dynamics of the open model
Johannes Lang, Michael Buchhold, Sebastian Diehl
A field theory approach for the nonequilibrium relaxation dynamics in open systems at late times is developed. In the absence of conservation laws, all excitations are subject to d…
Entanglement phases, localization and multifractality of monitored free fermions in two dimensions
K. Chahine, M. Buchhold
We investigate the entanglement structure and wave function characteristics of continuously monitored free fermions with U-symmetry in two spatial dimensions (2D). By deriving…
Majorana Loop Models for Measurement-Only Quantum Circuits
Kai Klocke, Michael Buchhold
Projective measurements in random quantum circuits lead to a rich breadth of entanglement phases and extend the realm of non-unitary quantum dynamics. Here we explore the connectio…
