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…

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…
