Baseband control of single-electron silicon spin qubits in two dimensions
Florian K. Unseld, Brennan Undseth, Eline Raymenants +9
Micromagnet-enabled electric-dipole spin resonance (EDSR) is an established method of high-fidelity single-spin control in silicon. However, the resulting architectural limitations…
A two-dimensional 10-qubit array in germanium with robust and localised qubit control
Valentin John, Cécile X. Yu, Barnaby van Straaten +10
Quantum computers require the systematic operation of qubits with high fidelity. For holes in germanium, the spin-orbit interaction allows for \textit{in situ} electric fast and hi…
Charge-induced energy shift of a single-spin qubit under a magnetic-field gradient
Takashi Kobayashi, Akito Noiri, Takashi Nakajima +5
An electron confined by a semiconductor quantum dot (QD) can be displaced by changes in electron occupations of surrounding QDs owing to the Coulomb interaction. For a single-spin…
Reducing disorder in Ge quantum wells by using thick SiGe barriers
Davide Costa, Lucas E. A. Stehouwer, Yi Huang +4
We investigate the disorder properties of two-dimensional hole gases in Ge/SiGe heterostructures grown on Ge wafers, using thick SiGe barriers to mitigate the influence of the semi…
Modular Autonomous Virtualization System for Two-Dimensional Semiconductor Quantum Dot Arrays
Anantha S. Rao, Donovan Buterakos, Barnaby van Straaten +8
Arrays of gate-defined semiconductor quantum dots are among the leading candidates for building scalable quantum processors. High-fidelity initialization, control, and readout of s…
Exploiting epitaxial strained germanium for scaling low noise spin qubits at the micron-scale
Lucas E. A. Stehouwer, Cécile X. Yu, Barnaby van Straaten +10
Disorder in the heterogeneous material stack of semiconductor spin qubit systems introduces noise that compromises quantum information processing, posing a challenge to coherently…
