Electron g-factor determined for quantum dot circuit fabricated from (110)-oriented GaAs quantum well
T. Nakagawa, S. Lamoureux, T. Fujita +8
The choice of substrate orientation for semiconductor quantum dot circuits offers opportunities for tailoring spintronic properties such as g-factors for specific functionality. In…
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…
Noise-robust classification of single-shot electron spin readouts using a deep neural network
Yuta Matsumoto, Takafumi Fujita, Arne Ludwig +3
Single-shot readout of charge and spin states by charge sensors such as quantum point contacts and quantum dots are essential technologies for the operation of semiconductor spin q…
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,…
Quantum state transfer of angular momentum via single electron photo-excitation from a Zeeman-resolved light hole
Kazuyuki Kuroyama, Marcus Larsson, Jo Muramoto +9
Electron spins in GaAs quantum dots have been used to make qubits with high-fidelity gating and long coherence time, necessary ingredients in solid-state quantum computing. The qua…
A single eletron-photon pair generation from a single polarization-entangled photon pair
Kazuyuki Kuroyama, Marcus Larsson, Sadashige Matsuo +6
We demonstrate paired generation of a single photo-electron in a quantum dot and a single photon from a single polarization-entangled photon pair that is generated by spontaneous p…
