Generalized Mathisson-Papapetrou-Tulczyjew-Dixon Equations

Takayoshi Ootsuka, Ryoko Yahagi

We derive two generalizations of Mathisson-Papapetrou-Tulczyjew-Dixon equations from Casalbuoni-Brink-Schwarz type pseudoclassical Lagrangians of Majorana spinors on a Riemann-Cart…

Two-level Quantum Walkers on Directed Graphs II: An Application to qRAM

Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi

This is the second paper in a series of two. Using a multi-particle continuous-time quantum walk with two internal states, which has been formulated in the first paper (arXiv:2112.…

Two-level Quantum Walkers on Directed Graphs I: Universal Quantum Computing

Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi

In the present paper, the first in a series of two, we propose a model of universal quantum computation using a fermionic/bosonic multi-particle continuous-time quantum walk with t…

Quantum random access memory via quantum walk

Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi

A novel concept of quantum random access memory (qRAM) employing a quantum walk is provided. Our qRAM relies on a bucket brigade scheme to access the memory cells. Introducing a bu…

Quantum circuit for the fast Fourier transform

Ryo Asaka, Kazumitsu Sakai, Ryoko Yahagi

We propose an implementation of the algorithm for the fast Fourier transform (FFT) as a quantum circuit consisting of a combination of some quantum gates. In our implementation, a…

Finsler connection in moving frame formalism

Takayoshi Ootsuka, Muneyuki Ishida, Ryoko Yahagi

In our previous work, we have defined a nonlinear connection of Finsler manifold which preserves the Finsler metric . To make the method easier and more useful in applic…
