A scheme for implementing the discrete-time quantum walk on the Bloch sphere is
proposed, which is closely related to the SU (2) group. A spin cluster serves as the walker …

We perform a finite-time scaling analysis over the detrapping point of a three-state quantum
walk on the line. The coin operator is parametrized by ρ that controls the wave packet …

Coined discrete-time quantum walks are studied using simple deterministic dynamical
systems as coins whose classical limit can range from being integrable to chaotic. It is …

Out-of-time-ordered correlators (OTOCs) have recently attracted significant attention, finding
applications in disparate areas, from the physics of many-body systems to quantum black …

We propose a scheme to implement the quantum walk for SU (1, 1) in the phase space,
which generalizes those associated with the Heisenberg-Weyl group. The movement of the …

This book presents new and prospective approaches to quantum computing. It introduces
the many possibilities to further develop the mathematical methods of quantum computation …
