Electrical detection of the Majorana fusion rule for chiral edge vortices in a topological superconductor
C. W. J. Beenakker, A. Grabsch, Y. Herasymenko
Majorana zero-modes bound to vortices in a topological superconductor have a non-Abelian exchange statistics expressed by a non-deterministic fusion rule: When two vortices merge t…
Deterministic creation and braiding of chiral edge vortices
C. W. J. Beenakker, P. Baireuther, Y. Herasymenko +3
Majorana zero-modes in a superconductor are midgap states localized in the core of a vortex or bound to the end of a nanowire. They are anyons with non-Abelian braiding statistics,…
Low-high voltage duality in tunneling spectroscopy of the Sachdev-Ye-Kitaev model
N. V. Gnezdilov, J. A. Hutasoit, C. W. J. Beenakker
The Sachdev-Ye-Kitaev (SYK) model describes a strongly correlated metal with all-to-all random interactions (average strength ) between fermions (complex Dirac fermions or r…
Valley switch in a graphene superlattice due to pseudo-Andreev reflection
C. W. J. Beenakker, N. V. Gnezdilov, E. Dresselhaus +4
Dirac electrons in graphene have a valley degree of freedom that is being explored as a carrier of information. In that context of "valleytronics" one seeks to coherently manipulat…
Neural network decoder for topological color codes with circuit level noise
P. Baireuther, M. D. Caio, B. Criger +2
A quantum computer needs the assistance of a classical algorithm to detect and identify errors that affect encoded quantum information. At this interface of classical and quantum c…
