Comparison of spin-qubit architectures for quantum error-correcting codes
Mauricio Gutiérrez, Juan S. Rojas-Arias, David Obando +1
We investigate the performance of two quantum error-correcting codes, the surface code and the Bacon-Shor code, for implementation with spin qubits in silicon. In each case, we con…
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…
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…
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…
The origins of noise in the Zeeman splitting of spin qubits in natural-silicon devices
Juan S. Rojas-Arias, Yohei Kojima, Kenta Takeda +7
We measure and analyze noise-induced energy-fluctuations of spin qubits defined in quantum dots made of isotopically natural silicon. Combining Ramsey, time-correlation of single-s…
