A Bravyi-König theorem for Floquet codes generated by locally conjugate instantaneous stabiliser groups
Jelena Mackeprang, Jonas Helsen
The Bravyi-König (BK) theorem is an important no-go theorem for the dynamics of topological stabiliser quantum error correcting codes. It states that any logical operation on a …

Will it glue? On short-depth designs beyond the unitary group
Lorenzo Grevink, Jonas Haferkamp, Markus Heinrich +4
We study the formation of short-depth designs beyond the unitary group. We provide a range of results on several groups of broad interest in quantum information science: the Cliffo…

Random regular graph states are complex at almost any depth
Soumik Ghosh, Dominik Hangleiter, Jonas Helsen
Graph states are fundamental objects in the theory of quantum information due to their simple classical description and rich entanglement structure. They are also intimately relate…
