Synchronized Stepwise Control of Firing and Learning Thresholds in a Spiking Randomly Connected Neural Network toward Hardware Implementation
Kumiko Nomura, Yoshifumi Nishi
We propose hardware-oriented models of intrinsic plasticity (IP) and synaptic plasticity (SP) for spiking randomly connected recursive neural network (RNN). Although the potential…
Quantum Annealing Machines Based on Semiconductor Nanostructures
Tetsufumi Tanamoto, Yoshifumi Nishi, Jun Deguchi
The development of quantum annealing machines (QAMs) based on superconducting qubits has progressed greatly in recent years and these machines are now widely used in both academia…
Accurate Model of a Vertical Pillar Quantum Dot
P. A. Maksym, Y. Nishi, D. G. Austing +4
An accurate model of a vertical pillar quantum dot is described. The full three dimensional structure of the device containing the dot is taken into account and this leads to an ef…
Fano-Kondo effect in a two-level system with triple quantum dots: shot noise characteristics
Tetsufumi Tanamoto, Yoshifumi Nishi, Shinobu Fujita
We theoretically compare transport properties of Fano-Kondo effect with those of Fano effect. We focus on shot noise characteristics of a triple quantum dot (QD) system in the Fano…
Fano-Kondo effect through two-level system based on quantum dots
Tetsufumi Tanamoto, Yoshifumi Nishi
We theoretically study the Fano-Kondo effect in a triple quantum dot (QD) system where two QDs constitute a two-level system and the other QD works in a detector with electrodes. W…
Intermediate Low Spin States in a Few-electron Quantum Dot in the Regime
Y. Nishi, P. A. Maksym, D. G. Austing +4
We study the effects of electron-electron interactions in a circular few-electron vertical quantum dot in such a strong magnetic field that the filling factor . We measure…
