Wide-band capacitance measurement on a semiconductor double quantum dot for studying tunneling dynamics
Takeshi Ota, Toshiaki Hayashi, Koji Muraki +1
We propose and demonstrate wide-band capacitance measurements on a semiconductor double-quantum dot (DQD) to study tunneling dynamics. By applying phase-tunable high-frequency sign…

Correlated coherent oscillations in coupled semiconductor charge qubits
Gou Shinkai, Toshiaki Hayashi, Takeshi Ota +1
Designing coherent processes is essential for developing quantum information technologies. We study coherent dynamics of two spatially separated electrons in a coupled semiconducto…

Electrical pump-and-probe study of spin singlet-triplet relaxation in a quantum dot
S. Sasaki, T. Fujisawa, T. Hayashi +1
Spin relaxation from a triplet excited state to a singlet ground state in a semiconductor quantum dot is studied by employing an electrical pump-and-probe method. Spin relaxation o…
