Remarks on the structure of Clifford quantum cellular automata
Dirk-Michael Schlingemann
We report here on the structure of reversible quantum cellular automata with the additional restriction that these are also Clifford operations. This means that tensor products of…

Braiding and entanglement in spin networks: a combinatorial approach to topological phases
Zoltan Kadar, Annalisa Marzuoli, Mario Rasetti
The spin network quantum simulator relies on the su(2) representation ring (or its q-deformed counterpart at q= root of unity) and its basic features naturally include (multipartit…

On Haag Duality for Pure States of Quantum Spin Chain
M. Keyl, Taku Matsui, D. Schlingemann +1
We consider quantum spin chains and their translationally invariant pure states. We prove Haag duality for quasilocal observables localized in semi-infinite intervals when the von…
