Monodromy analysis of the computational power of the Ising topological quantum computer
Andre Ahlbrecht, Lachezar S. Georgiev, Reinhard F. Werner
We show that all quantum gates which could be implemented by braiding of Ising anyons in the Ising topological quantum computer preserve the n-qubit Pauli group. Analyzing the stru…
Bounds on the Speedup in Quantum signalling
Pablo Arrighi, Vincent Nesme, Reinhard Werner
Given a discrete reversible dynamics, we can define a quantum dynamics, which acts on basis states like the classical one, but also allows for superpositions of them. It is a curio…
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…
Time Asymptotics and Entanglement Generation of Clifford Quantum Cellular Automata
Johannes Gütschow, Sonja Uphoff, Reinhard F. Werner +1
We consider Clifford Quantum Cellular Automata (CQCAs) and their time evolution. CQCAs are an especially simple type of Quantum Cellular Automata, yet they show complex asymptotics…
