Coherent electron splitting in interacting chiral edge channels

Eiki Iyoda, Takase Shimizu, Masayuki Hashisaka

This paper theoretically studies the quantum coherence of an electronic state on an artificial chiral Tomonaga-Luttinger (TL) liquid. Coulomb interaction between copropagating inte…

Mach-Zehnder interference of fractionalized electron-spin excitations

Takase Shimizu, Eiki Iyoda, Satoshi Sasaki +4

Inter-channel Coulomb interaction mixes charge excitations in copropagating quantum Hall edge channels, generating coupled excitation eigenmodes propagating at different speeds. Th…

Fast time-domain current measurement for quantum dot charge sensing using a homemade cryogenic transimpedance amplifier

Heorhii Bohuslavskyi, Masayuki Hashisaka, Takase Shimizu +3

We developed a high-speed and low-noise time-domain current measurement scheme using a homemade GaAs high-electron-mobility-transistor-based cryogenic transimpedance amplifier (TIA…

Half-mirror for electrons on quantum Hall copropagating edge channels

Takase Shimizu, Jun-ichiro Ohe, Akira Endo +2

A half-mirror that divides a spin-polarized electron into two parallel copropagating spin-resolved quantum Hall edge channels one half each is presented in this study. The partitio…

Gate controlled unitary operation on flying spin qubits in quantum Hall edge states

Takase Shimizu, Taketomo Nakamura, Yoshiaki Hashimoto +2

Spin and orbital freedoms of electrons traveling on spin-resolved quantum Hall edge states (quantum Hall ferromagnets) are maximally entangled. The unitary operations on these two…
