Charge state estimation in quantum dots using a Bayesian approach
Motoya Shinozaki, Yui Muto, Takahito Kitada +1
Detection of single-electron charges in solid-state nanodevices is a key technique in semiconductor quantum bit readout for quantum information processing and probing electronic pr…
Channel length dependence of the formation of quantum dots in GaN/AlGaN FETs
Kazuma Matsumura, Takaya Abe, Takahito Kitada +5
Quantum dots can be formed in simple GaN/AlGaN field-effect-transistors (FETs) by disordered potential induced by impurities and defects. Here, we investigate the channel length de…
Visual explanations of machine learning model estimating charge states in quantum dots
Yui Muto, Takumi Nakaso, Motoya Shinozaki +13
Charge state recognition in quantum dot devices is important in the preparation of quantum bits for quantum information processing. Toward auto-tuning of larger-scale quantum devic…
Gate voltage dependence of noise distribution in radio-frequency reflectometry in gallium arsenide quantum dots
Motoya Shinozaki, Yui Muto, Takahito Kitada +10
We investigate gate voltage dependence of electrical readout noise in high-speed rf reflectometry using gallium arsenide quantum dots. The fast Fourier transform spectrum from the…
Formation of quantum dots in GaN/AlGaN FETs
Tomohiro Otsuka, Takaya Abe, Takahito Kitada +3
GaN and the heterostructures are attractive in condensed matter science and applications for electronic devices. We measure the electron transport in GaN/AlGaN field-effect transis…
