InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Full configuration interaction simulations of exchange-coupled donors in silicon using multi-valley effective mass theory
Benjamin Joecker, Andrew D. Baczewski, John K. Gamble +3
Donor spin in silicon have achieved record values of coherence times and single-qubit gate fidelities. The next stage of development involves demonstrating high-fidelity two-qubit…
Repairing the Surface of InAs-based Topological Heterostructures
S. J. Pauka, J. D. S. Witt, C. N. Allen +9
Candidate systems for topologically-protected qubits include two-dimensional electron gases (2DEGs) based on heterostructures exhibiting a strong spin-orbit interaction (SOI) and s…
Adiabatic two-qubit gates in capacitively coupled quantum dot hybrid qubits
Adam Frees, Sebastian Mehl, John King Gamble +2
The ability to tune qubits to flat points in their energy dispersions ("sweet spots") is an important tool for mitigating the effects of charge noise and dephasing in solid-state d…
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…
Spectroscopy of multi-electrode tunnel barriers
A. Shirkhorshidian, John King Gamble, L. Maurer +8
Despite their ubiquity in nanoscale electronic devices, the physics of tunnel barriers has not been developed to the extent necessary for the engineering of devices in the few-elec…
