High-fidelity spin readout via the double latching mechanism
Haruki Kiyama, Danny van Hien Hien, Arne Ludwig +2
Projective measurement of single electron spins, or spin readout, is among the most fundamental technologies for spin-based quantum information processing. Implementing spin readou…
Preparation and Readout of Multielectron High-Spin States in a Gate-Defined GaAs/AlGaAs Quantum Dot
H. Kiyama, K. Yoshimi, T. Kato +3
We report the preparation and readout of multielectron high-spin states, a three-electron quartet, and a four-electron quintet, in a gate-defined GaAs/AlGaAs single quantum dot usi…
Single-electron charge sensing in self-assembled quantum dots
Haruki Kiyama, Alexander Korsch, Naomi Nagai +4
Measuring single-electron charge is one of the most fundamental quantum technologies. Charge sensing, which is an ingredient for the measurement of single spins or single photons,…
Single photoelectron spin detection and angular momentum transfer in a gate defined quantum dot
Takafumi Fujita, Kazuhiro Morimoto, Haruki Kiyama +7
Recent innovations in fabricating nanoscale confined spin systems have enabled investigation of fundamental quantum correlations between single quanta of photons and matter states.…
Spin-dependent current through a quantum dot from spin-polarized non-equilibrium quantum Hall edge channels
Haruki Kiyama, Takashi Nakajima, Soichiro Teraoka +2
We report selective injection of both spin-up and spin-down single electrons into a quantum dot (QD) from spin-polarized non-equilibrium quantum Hall edge channels (ECs) generated…
Tuning the electrically evaluated electron Lande g factor in GaAs quantum dots and quantum wells of different well widths
G. Allison, T. Fujita, K. Morimoto +9
We evaluate the Lande g factor of electrons in quantum dots (QDs) fabricated from GaAs quantum well (QW) structures of different well width. We first determine the Lande electron g…
Single Photoelectron Detection after Selective Excitation of Electron-Heavy Hole and Electron-Light Hole Pairs in Double Quantum Dots
K. Morimoto, T. Fujita, G. Allison +9
We demonstrate the real-time detection of single photogenerated electrons in two different lateral double quantum dots made in AlGaAs/GaAs/AlGaAs quantum wells having a thin or a t…
