Localization in the constrained quantum annealing of graph coloring
Kazue Kudo
Constrained quantum annealing (CQA) is a quantum annealing approach that is designed so that constraints are satisfied without penalty terms. There is an analogy between the model…
Constrained quantum annealing of graph coloring
Kazue Kudo
We investigate a quantum annealing approach based on real-time quantum dynamics for graph coloring. In this approach, a driving Hamiltonian is chosen so that constraints are natura…
Level statistics of a pseudo-Hermitian Dicke model
Tetsuo Deguchi, Pijush K. Ghosh, Kazue Kudo
A non-Hermitian operator that is related to its adjoint through a similarity transformation is defined as a pseudo-Hermitian operator. We study the level-statistics of a pseudo-Her…
Quantum transport and spin dynamics on shearless tori
K. Kudo, T. S. Monteiro
We investigate for quantum dynamics in phase-space regions containing ``shearless tori''. We show that the properties of these peculiar classical phase-space structures -- importan…
