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…
Compressed Optimization of Device Architectures (CODA) for semiconductor quantum devices
Adam Frees, John King Gamble, Daniel R. Ward +4
Recent advances in nanotechnology have enabled researchers to manipulate small collections of quantum mechanical objects with unprecedented accuracy. In semiconductor quantum dot q…
The critical role of substrate disorder in valley splitting in Si quantum wells
Samuel F. Neyens, Ryan H. Foote, Brandur Thorgrimsson +11
Motivated by theoretical predictions that spatially complex concentration modulations of Si and Ge can increase the valley splitting in quantum wells, we grow and characterize Si/S…
