Asymptotic evolution of quantum walks with random coin
Andre Ahlbrecht, Holger Vogts, Albert H. Werner +1
We study the asymptotic position distribution of general quantum walks on a lattice, including walks with a random coin, which is chosen from step to step by a general Markov chain…
Index theory of one dimensional quantum walks and cellular automata
D. Gross, V. Nesme, H. Vogts +1
If a one-dimensional quantum lattice system is subject to one step of a reversible discrete-time dynamics, it is intuitive that as much "quantum information" as moves into any give…
On the structure of Clifford quantum cellular automata
Dirk-M. Schlingemann, Holger Vogts, Reinhard F. Werner
We study reversible quantum cellular automata with the restriction that these are also Clifford operations. This means that tensor products of Pauli operators (or discrete Weyl ope…
