Reservoir- and Measurement-free Microwave Initialization of Semiconductor Spin Qubits
Leon C. Camenzind, Ik Kyeong Jin, Akito Noiri +4
Scalable quantum processors require repeated qubit initialization throughout large arrays. In semiconductor spin qubits, fast initialization commonly relies on local reservoir acce…
Assessing fidelity-limiting factors and achieving single-qubit gate fidelity beyond 99.999% in driven silicon spin qubits
Kenta Takeda, Akito Noiri, Takashi Nakajima +4
In semiconductor single-spin qubits, high-fidelity quantum gates have been demonstrated; however, achieving consistent performance remains challenging due to variations in driven q…
Scaling of silicon spin qubits under correlated noise
Juan S. Rojas-Arias, Leon C. Camenzind, Yi-Hsien Wu +8
The path to fault-tolerant quantum computing hinges on hardware that scales while remaining compatible with quantum error correction (QEC). Silicon spin qubits are a leading hardwa…
Simultaneous High-Fidelity Single-Qubit Gates in a Spin Qubit Array
Yi-Hsien Wu, Leon C. Camenzind, Patrick Bütler +8
Silicon spin qubits offer a promising path to scalable quantum computing due to their compatibility with industrial semiconductor manufacturing and recent advances in multi-qubit i…
Inferring charge-noise source locations from correlations in spin qubits
Juan S. Rojas-Arias, Akito Noiri, Jun Yoneda +7
We investigate low-frequency noise in a spin-qubit device made in isotopically purified Si/Si-Ge. Observing sizable cross-correlations among energy fluctuations of different qubits…
Charge-induced energy shift of a single-spin qubit under a magnetic-field gradient
Takashi Kobayashi, Akito Noiri, Takashi Nakajima +5
An electron confined by a semiconductor quantum dot (QD) can be displaced by changes in electron occupations of surrounding QDs owing to the Coulomb interaction. For a single-spin…
