SiMOS quantum-dot spin qubits enabled by extreme-ultraviolet lithography
Thomas Van Caekenberghe, Paul Steinacker, Bart Raes +31
The authors fabricate silicon MOS spin qubits using extreme‑ultraviolet (EUV) lithography on 300 mm wafers and demonstrate sub‑nanometer gate control, high uniformity, and gate fid…
Understanding oxide-thickness-dependent variability in dense Si-MOS quantum dot arrays
Arne Loenders, Jacques Van Damme, Clement Godfrin +19
Achieving uniform and scalable control of semiconductor spin qubits remains a key challenge for large scale quantum computing. In this work, we investigate how gate oxide thickness…
Microscopic modeling of flopping-mode quantum dot spin qubits
Ashutosh Kinikar, Vukan Levajac, Kristof Moors +3
We present a flexible microscopic modeling framework for flopping-mode spin qubits that captures the spatial structure of the double-well confinement and magnetic-field-gradient pr…
Long coherence silicon spin qubit fabricated in a 300 mm industrial foundry
Petar TomiÄ, Patrick Bütler, Yuze Wu +17
Silicon spin qubits offer long coherence times, a compact footprint and compatibility with industrial CMOS manufacturing. Here, we investigate spin qubits hosted in quantum dots fa…
Qudit vs. Qubit: Simulated performance of error correction codes in higher dimensions
James Keppens, Quinten Eggerickx, Vukan Levajac +2
Qudits can be described by a state vector in a -dimensional Hilbert space, enabling a more extensive encoding and manipulation of information compared to qubits. This implies th…
Current Conservation in the Self-Consistent Josephson Junction
Simon Krekels, Vukan Levajac, Kristof Moors +2
Conventional treatments of Josephson junctions (JJs) are typically not current-conserving. In the mean-field BCS theory, current conservation is only guaranteed if the superconduct…
