Many-body-localization protection of eigenstate topological order in two dimensions
Florian Venn, Thorsten B. Wahl, Benjamin Béri
Many-body localization (MBL) has been proposed to enable and protect topological order in all eigenstates, vastly expanding the traditional ground-state setting. However, for the m…
Surface codes, quantum circuits, and entanglement phases
Jan Behrends, Florian Venn, Benjamin Béri
Surface codes$\unicode{x2014}$leading candidates for quantum error correction (QEC)$\unicode{x2014}$and entanglement phases$\unicode{x2014}$a key notion for many-body quantum dynam…
Coherent error threshold for surface codes from Majorana delocalization
Florian Venn, Jan Behrends, Benjamin Béri
Statistical mechanics mappings provide key insights on quantum error correction. However, existing mappings assume incoherent noise, thus ignoring coherent errors due to, e.g., spu…
Local integrals of motion detection of localization-protected topological order
Thorsten B. Wahl, Florian Venn, Benjamin Béri
Many-body-localized (MBL) phases can be topologically distinct, but distinguishing these phases using order parameters can be challenging. Here we show how topologically distinct l…
Error-correction and noise-decoherence thresholds for coherent errors in planar-graph surface codes
F. Venn, B. Béri
We numerically study coherent errors in surface codes on planar graphs, focusing on noise of the form of - or -rotations of individual qubits. We find that, similarly to the…
Aharonov-Bohm oscillations and magnetic focusing in ballistic graphene rings
Jan Dauber, Martin Oellers, Florian Venn +5
We present low-temperature magnetotransport measurements on graphene rings encapsulated in hexagonal boron nitride. We investigate phase-coherent transport and show Aharonov-Bohm (…
