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…
Fidelity Analysis of Adiabatically Driven Donor Spins as Two-Qubit and Ququart Systems
Brian Michon, James Keppens, Ashutosh Kinikar +3
Donor spin systems host a native Hilbert space whose dimension exceeds that of a qubit, meaning they can be used as qudits. Here we study a \ce{Si{:}P} donor spin system through le…
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…
Distributed Current Injection into a One-Dimensional Ballistic Edge Channel
Kristof Moors, Christian Wagner, Helmut Soltner +3
We generalize Landauer's theory of ballistic transport in a one-dimensional (1D) conductor to situations where charge carrier injection and extraction are not any more confined to…
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…
