Evaluation of Circular Complex Permeability in Single-Crystal Yttrium Iron Garnet at Cryogenic Temperatures
Junta Igarashi, Shota Norimoto, Hiroyuki Kayano +4
The operation of superconducting qubits requires a sensitive readout circuit at cryogenic temperatures, driving the demand for cryogenic non reciprocal microwave components such as…
Statistical study and parallelisation of multiplexed single-electron sources
S. Norimoto, P. See, N. Schoinas +7
Increasing electric current from a single-electron source is a main challenge in an effort to establish the standard of the ampere defined by the fixed value of the elementary char…
Photon emission by hot electron injection across a lateral \textit{pn} junction
S. Norimoto, R. Saxena, P. See +5
We demonstrate a method to generate photons by injecting hot electrons into a {\it pn} junction within a \ce{GaAs/AlGaAs} heterostructure. Hot electrons are generated by biasing ac…
Fast characterization of multiplexed single-electron pumps with machine learning
N. Schoinas, Y. Rath, S. Norimoto +8
We present an efficient machine learning based automated framework for the fast tuning of single-electron pump devices into current quantization regimes. It uses a sparse measureme…
Large Zeeman Splitting in Out-of-Plane Magnetic Field in a Double-Layer Quantum Point Contact
D. Terasawa, S. Norimoto, T. Arakawa +4
In this study, we observe that the conductance of a quantum point contact on a GaAs/AlGaAs double quantum well depends significantly on the magnetic field perpendicular to the two-…
Etching process of narrow wire and application to tunable-barrier electron pump
Shota Norimoto, Shuichi Iwakiri, Masahiko Yokoi +3
Single electron sources have been studied as a device to establish an electric current standard for 30 years and recently as an on-demand coherent source for Fermion quantum optics…
Conductance quantization and shot noise of a double-layer quantum point contact
D. Terasawa, S. Norimoto, T. Arakawa +4
The conductance quantization and shot noise below the first conductance plateau are measured in a quantum point contact fabricated in a GaAs/AlGaAs tunnel-coupled do…
Finite shot noise and electron heating at quantized conductance in high-mobility quantum point contacts
Tatsuya Muro, Yoshitaka Nishihara, Shota Norimoto +8
We report a precise experimental study on the shot noise of a quantum point contact (QPC) fabricated in a GaAs/AlGaAs based high-mobility two-dimensional electron gas (2DEG). The c…
