Quantum tangent kernel
Norihito Shirai, Kenji Kubo, Kosuke Mitarai +1
Quantum kernel method is one of the key approaches to quantum machine learning, which has the advantages that it does not require optimization and has theoretical simplicity. By vi…
Pricing multi-asset derivatives by finite difference method on a quantum computer
Koichi Miyamoto, Kenji Kubo
Following the recent great advance of quantum computing technology, there are growing interests in its applications to industries, including finance. In this paper, we focus on der…
Variational quantum simulations of stochastic differential equations
Kenji Kubo, Yuya O. Nakagawa, Suguru Endo +1
Stochastic differential equations (SDEs), which models uncertain phenomena as the time evolution of random variables, are exploited in various fields of natural and social sciences…
Anisotropic spin motive force in multi-layered Dirac fermion system, -(BEDT-TTF)I
K. Kubo, T. Morinari
We investigate the anisotropic spin motive force in -(BEDT-TTF)I, which is a multi-layered massless Dirac fermion system under pressure. Assuming the interlayer antiferr…
Spin-Ordered States in Multilayer Massless Dirac Fermion Systems
Kenji Kubo, Takao Morinari
We investigate the spin-ordered states in multilayer massless Dirac fermion systems under magnetic fields, in which the intralayer interaction is ferromagnetic owing to the exchang…
Effect of Interlayer Spin-Flip Tunneling for Interlayer Magnetoresistance in Multilayer Massless Dirac Fermion Systems
Kenji Kubo, Takao Morinari
We investigate the effect of the interlayer spin-flip tunneling for the interlayer magnetoresistance under magnetic fields in alpha-(BEDT-TTF)2I3, which is a multilayer massless Di…
