Deterministic and random features for large-scale quantum kernel machine

Kouhei Nakaji, Hiroyuki Tezuka, Naoki Yamamoto

Quantum machine learning (QML) is the spearhead of quantum computer applications. In particular, quantum neural networks (QNN) are actively studied as the method that works both in…

Quantum semi-supervised generative adversarial network for enhanced data classification

Kouhei Nakaji, Naoki Yamamoto

In this paper, we propose the quantum semi-supervised generative adversarial network (qSGAN). The system is composed of a quantum generator and a classical discriminator/classifier…

Expressibility of the alternating layered ansatz for quantum computation

Kouhei Nakaji, Naoki Yamamoto

The hybrid quantum-classical algorithm is actively examined as a technique applicable even to intermediate-scale quantum computers. To execute this algorithm, the hardware efficien…

LHC signature with long-lived stau in high reheating temperature scenario

Motoi Endo, Koichi Hamaguchi, Kouhei Nakaji

We study the possibility of observing the stau signal at LHC in case that the gravitino is the lightest supersymmetric particle and the stau is the next lightest supersymmetric par…

Inverse Problem of Cosmic-Ray Electron/Positron from Dark Matter

Koichi Hamaguchi, Kouhei Nakaji, Eita Nakamura

We discuss the possibility of solving the inverse problem of the cosmic-ray electron/positron from decaying/annihilating dark matter, and show simple analytic formulae to reconstru…
