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…
Simultaneous High-Fidelity Single-Qubit Gates in a Spin Qubit Array
Yi-Hsien Wu, Leon C. Camenzind, Patrick Bütler +8
The paper demonstrates high-fidelity single-qubit gates in a five-qubit silicon spin array, achieving >99.99% fidelity for individual and up to three simultaneous qubits by mitigat…
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…
Noise cross-correlations from single-shot measurements
Juan S. Rojas-Arias, Peter Stano, Yi-Hsien Wu +3
We introduce a novel method that we call Single-Shot Cross-Spectroscopy (SSCS), for extracting the auto- and cross-power spectral densities of dephasing noise of a qubit pair. The…
Compromise-Free Scaling of Qubit Speed and Coherence
Miguel J. Carballido, Simon Svab, Rafael S. Eggli +12
Across leading qubit platforms, a common trade-off persists: increasing coherence comes at the cost of operational speed, reflecting the notion that protecting a qubit from its noi…
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…
