Difference in charge and spin dynamics in a quantum dot-lead coupled system
Tomohiro Otsuka, Takashi Nakajima, Matthieu R. Delbecq +12
We analyze time evolution of charge and spin states in a quantum dot coupled to an electric reservoir. Utilizing high-speed single-electron detection, we focus on dynamics induced…
Four single-spin Rabi oscillations in a quadruple quantum dot
Takumi Ito, Tomohiro Otsuka, Takashi Nakajima +9
Scaling up qubits is a necessary step to realize useful systems of quantum computation. Here we demonstrate coherent manipulations of four individual electron spins using a micro-m…
A fast quantum interface between different spin qubit encodings
A. Noiri, T. Nakajima, J. Yoneda +12
Single-spin qubits in semiconductor quantum dots proposed by Loss and DiVincenzo (LD qubits) hold promise for universal quantum computation with demonstrations of a high single-qub…
