A method of approximation of discrete Schrödinger equation with the normalized Laplacian by discrete-time quantum walk on graphs
Kei Saito, Etsuo Segawa
We propose a class of continuous-time quantum walk models on graphs induced by a certain class of discrete-time quantum walk models with the parameter . Here the graph…
Resonance expansion for quantum walks and its applications to the long-time behavior
Kenta Higuchi, Hisashi Morioka, Etsuo Segawa
In this paper, resonances are introduced to a class of quantum walks on . Resonances are defined as poles of the meromorphically extended resolvent of the unitary time…
Bandit Algorithm Driven by a Classical Random Walk and a Quantum Walk
Tomoki Yamagami, Etsuo Segawa, Takatomo Mihana +3
Quantum walks (QWs) have a property that classical random walks (RWs) do not possess -- the coexistence of linear spreading and localization -- and this property is utilized to imp…
Asymmetric quantum decision-making
Honoka Shiratori, Hiroaki Shinkawa, André Röhm +7
Collective decision-making is crucial to information and communication systems. Decision conflicts among agents hinder the maximization of potential utilities of the entire system.…
