Spectroscopy With Intelligent Feature Tracking for automated characterization of excited-state structure in semiconductor quantum dot devices
A. R. Huffman, Daniel Schug, Merritt Losert +6
The characterization of excited-state structure in semiconductor quantum dot (QD) devices is an important component of tuning them for spin-qubit operation. We present Spectroscopy…
Using a spin-triplet encoding to enhance shuttling fidelities in Si/SiGe quantum wells
Merritt P. R. Losert, S. N. Coppersmith, Mark Friesen
Spatial variations of the valley splitting in a quantum well present a key challenge for conveyor-mode shuttling of electron spins in Si/SiGe, giving rise to Landau-Zener-like exci…
Automated electrostatic characterization of quantum dot devices in single- and bilayer heterostructures
Merritt P. R. Losert, Dario Denora, Barnaby van Straaten +6
As quantum dot (QD)-based spin qubits advance toward larger, more complex device architectures, rapid, automated device characterization and data analysis tools become critical. Th…
The effects of alloy disorder on strongly-driven flopping mode qubits in Si/SiGe
Merritt P. R. Losert, Utkan Güngördü, S. N. Coppersmith +2
In Si quantum dot systems, large magnetic field gradients are needed to implement spin rotations via electric dipole spin resonance (EDSR). By increasing the effective electron dip…
Statistical characterization of valley coupling in Si/SiGe quantum dots via -factor measurements near a valley vortex
Benjamin D. Woods, Merritt P. Losert, Nasir R. Elston +5
The presence of low-energy valley excitations in Si/SiGe heterostructures often causes spin qubits to fail. It is therefore important to develop robust protocols for characterizing…
Engineering Ge profiles in Si/SiGe heterostructures for increased valley splitting
Lucas E. A. Stehouwer, Merrit P. Losert, Maia Rigot +6
Electron spin qubits in Si/SiGe quantum wells are limited by the small and variable energy separation of the conduction band valleys. While sharp quantum well interfaces are pursue…
