Designs for a two-dimensional Si quantum dot array with spin qubit addressability
Masahiro Tadokoro, Takashi Nakajima, Takashi Kobayashi +6
Electron spins in Si are an attractive platform for quantum computation, backed with their scalability and fast, high-fidelity quantum logic gates. Despite the importance of two-di…
Real-Time Feedback Control of Charge Sensing for Quantum Dot Qubits
Takashi Nakajima, Yohei Kojima, Yoshihiro Uehara +4
Measurement of charge configurations in few-electron quantum dots is a vital technique for spin-based quantum information processing. While fast and high-fidelity measurement is po…
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…
Probabilistic teleportation of a quantum dot spin qubit
Y. Kojima, T. Nakajima, A. Noiri +8
Electron spin s in semiconductor quantum dot s have been intensively studied for implementing quantum computation and high fidelity single and two qubit operation s have recently b…
Quantum tomography of an entangled three-spin state in silicon
Kenta Takeda, Akito Noiri, Takashi Nakajima +3
Quantum entanglement is a fundamental property of coherent quantum states and an essential resource for quantum computing. While two-qubit entanglement has been demonstrated for sp…
Spin orbit field in a physically defined p type MOS silicon double quantum dot
Marian Marx, Jun Yoneda, Ángel Gutiérrez Rubio +10
We experimentally and theoretically investigate the spin orbit (SO) field in a physically defined, p type metal oxide semiconductor double quantum dot in silicon. We measure the ma…
