Co-tunneling spin blockade observed in a three-terminal triple quantum dot
A. Noiri, T. Takakura, T. Obata +4
We prepare a triple quantum dot with a separate contact lead to each dot to study Pauli spin blockade in the tunnel-coupled three dots in a row. We measure the tunneling current fl…
A >99.9%-fidelity quantum-dot spin qubit with coherence limited by charge noise
J. Yoneda, K. Takeda, T. Otsuka +10
Recent advances towards spin-based quantum computation have been primarily fuelled by elaborate isolation from noise sources, such as surrounding nuclear spins and spin-electric su…
A triangular triple quantum dot with tunable tunnel couplings
A. Noiri, K. Kawasaki, T. Otsuka +9
A two-dimensional arrangement of quantum dots with finite inter-dot tunnel coupling provides a promising platform for studying complicated spin correlations as well as for construc…
Robust Single-Shot Spin Measurement with 99.5% Fidelity in a Quantum Dot Array
Takashi Nakajima, Matthieu R. Delbecq, Tomohiro Otsuka +11
We demonstrate a new method for projective single-shot measurement of two electron spin states (singlet versus triplet) in an array of gate-defined lateral quantum dots in GaAs. Th…
