Symmetry-induced magnetic fullerene
Jiaqi Wu, Leonard Werner Pingen, Timothy K. Dickens +3
Defect-free, charge-neutral, pure-carbon materials are generally viewed as intrinsically non-magnetic. Here we challenge this view by establishing a fundamental principle of symmet…
Tunable quantum anomalous Hall effect in fullerene monolayers
Leonard Werner Pingen, Jiaqi Wu, Bo Peng
Nearly four decades after its theoretical prediction, the search for material realizations of quantum anomalous Hall effect (QAHE) remains a highly active field of research. Many m…
Probing the Physical Reality of Projective Measurements
Leonard Werner Pingen, Mattia Moroder, Sebastian Paeckel
We propose a protocol to test whether the postulate of a measurement acting as an instantaneous projection onto an eigenstate of the measurement apparatus is compatible with physic…
A logical qubit-design with geometrically tunable error-resistibility
Reja H. Wilke, Leonard W. Pingen, Thomas Köhler +1
Breaking the error-threshold would mark a milestone in establishing quantum advantage for a wide range of relevant problems. One possible route is to encode information redundantly…
