A trilinear quantum dot architecture for semiconductor spin qubits
R. Li, V. Levajac, C. Godfrin +10
Semiconductor quantum dot spin qubits hold significant potential for scaling to millions of qubits for practical quantum computing applications, as their structure highly resembles…
Investigation of microwave loss induced by oxide regrowth in high-Q Nb resonators
J. Verjauw, A. PotoÄnik, M. Mongillo +16
The coherence of state-of-the-art superconducting qubit devices is predominantly limited by two-level-system defects, found primarily at amorphous interface layers. Reducing microw…
A flexible 300 mm integrated Si MOS platform for electron- and hole-spin qubits exploration
R. Li, N. I. Dumoulin Stuyck, S. Kubicek +12
We report on a flexible 300 mm process that optimally combines optical and electron beam lithography to fabricate silicon spin qubits. It enables on-the-fly layout design modificat…
Two dimensional electron liquid in the presence of Rashba spin-orbit coupling: symmetric momentum space occupation states
S. Chesi, G. Simion, G. F. Giuliani
The orientation of the local electron spin quantization axis in momentum space is identified as the most significant physical variable in determining the states of a two-dimensiona…
Binary imposters: Mergers in massive hierarchical triple stars
F. Kummer, G. Simion, S. Toonen +1
Massive stars are often born in triples, where gravitational dynamics and stellar interactions play a crucial role in shaping their evolution. One such pathway includes the merger…
Uniform Spin Qubit Devices in an All-Silicon 300 mm Integrated Process
N. I. Dumoulin Stuyck, R. Li, C. Godfrin +12
Larger arrays of electron spin qubits require radical improvements in fabrication and device uniformity. Here we demonstrate excellent qubit device uniformity and tunability from 3…
