SiGe quantum wells with oscillating Ge concentrations for quantum dot qubits
Thomas McJunkin, Benjamin Harpt, Yi Feng +10
Large-scale arrays of quantum-dot spin qubits in Si/SiGe quantum wells require large or tunable energy splittings of the valley states associated with degenerate conduction band mi…
Toward Robust Autotuning of Noisy Quantum Dot Devices
Joshua Ziegler, Thomas McJunkin, E. S. Joseph +7
The current autotuning approaches for quantum dot (QD) devices, while showing some success, lack an assessment of data reliability. This leads to unexpected failures when noisy or…
Repetitive quantum non-demolition measurement and soft decoding of a silicon spin qubit
Xiao Xue, Benjamin D'Anjou, Thomas F. Watson +8
Quantum error correction is of crucial importance for fault-tolerant quantum computers. As an essential step towards the implementation of quantum error-correcting codes, quantum n…
Auto-tuning of double dot devices in situ with machine learning
Justyna P. Zwolak, Thomas McJunkin, Sandesh S. Kalantre +7
The current practice of manually tuning quantum dots (QDs) for qubit operation is a relatively time-consuming procedure that is inherently impractical for scaling up and applicatio…
Benchmarking Gate Fidelities in a Si/SiGe Two-Qubit Device
X. Xue, T. F. Watson, J. Helsen +7
We report the first complete characterization of single-qubit and two-qubit gate fidelities in silicon-based spin qubits, including cross-talk and error correlations between the tw…
A fast "hybrid" silicon double quantum dot qubit
Zhan Shi, C. B. Simmons, J. R. Prance +9
We propose a quantum dot qubit architecture that has an attractive combination of speed and fabrication simplicity. It consists of a double quantum dot with one electron in one dot…
