Hadamard Rigidity of Positive Sojourn Time Distributions for Rotation Coins
Shunya Tamura, Tomoki Yamagami
We study the distribution of the positive sojourn time for a one-dimensional two state quantum walk, conditioned on return to the origin. Konno showed that, for the Hadamard walk,…
Quantum spatial best-arm identification via quantum walks
Tomoki Yamagami, Etsuo Segawa, Takatomo Mihana +3
Quantum reinforcement learning has emerged as a framework combining quantum computation with sequential decision-making, and applications to the multi-armed bandit (MAB) problem ha…
Multi-player conflict avoidance through entangled quantum walks
Honoka Shiratori, Tomoki Yamagami, Etsuo Segawa +3
Quantum computing has the potential to solve complex problems faster and more efficiently than classical computing. It can achieve speedups by leveraging quantum phenomena like sup…
Normal variance mixture with arcsine law of an interpolating walk between persistent random walk and quantum walk
Saori Yoshino, Honoka Shiratori, Tomoki Yamagami +2
We propose a model that interpolates between quantum walks and persistent (correlated) random walks using one parameter on the one-dimensional lattice. We show that the limit distr…
General condition of quantum teleportation by one-dimensional quantum walks
Tomoki Yamagami, Etsuo Segawa, Norio Konno
We extend the scheme of quantum teleportation by quantum walks introduced by Wang et al. (2017). First, we introduce the mathematical definition of the accomplishment of quantum te…
