Simon's Algorithm for the Even-Mansour Cipher on Quantum Hardware
Anina Köhler, Jakob Murauer, Tim Heine +2
Simon's algorithm is a polynomial period-finding algorithm that has been used to exploit the algebraic structure of specific symmetric ciphers, showing that exponential speedups in…

The Witt rings of many flag varieties are exterior algebras
Tobias Hemmert, Marcus Zibrowius
The Witt ring of a complex flag variety describes the interesting -- i.e. torsion -- part of its topological KO-theory. We show that for a large class of flag varieties, these Witt…

KO-theory of complex flag varieties of ordinary type
Tobias Hemmert
We compute the topological Witt groups of every complex flag manifold of ordinary type, and thus the interesting (i.e. torsion) part of the KO-groups of these manifolds. Equivalent…
