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…
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…
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…
Coherence of a driven electron spin qubit actively decoupled from quasi-static noise
Takashi Nakajima, Akito Noiri, Kento Kawasaki +11
The coherence of electron spin qubits in semiconductor quantum dots suffers mostly from low-frequency noise. During the last decade, efforts have been devoted to mitigate such nois…
Repetitive single electron spin readout in silicon
J. Yoneda, K. Takeda, A. Noiri +5
Single electron spins confined in silicon quantum dots hold great promise as a quantum computing architecture with demonstrations of long coherence times, high-fidelity quantum log…
