3D tomography of exchange phase in a Si/SiGe quantum dot device
Dylan Albrecht, Sarah Thompson, N. Tobias Jacobson +1
The exchange interaction is a foundational building block for the operation of spin-based quantum processors. Extracting the exchange interaction coefficient , as a…
Multi-level charge fluctuations in a Si/SiGe double quantum dot device
Dylan Albrecht, Feiyang Ye, N. Tobias Jacobson +1
Discrete charge fluctuations, routinely observed in semiconductor quantum dot devices, may contribute significantly to device drift and errors resulting from qubit miscalibration.…
Model validation and error attribution for a drifting qubit
Malick A. Gaye, Dylan Albrecht, Steve Young +2
Qubit performance is often reported in terms of a variety of single-value metrics, each providing a facet of the underlying noise mechanism limiting performance. However, the value…
Characterization of individual charge fluctuators in Si/SiGe quantum dots
Feiyang Ye, Ammar Ellaboudy, Dylan Albrecht +3
Electron spins in silicon quantum dots are excellent qubits due to their long coherence times, scalability, and compatibility with advanced semiconductor technology. Although high…
