SiMOS quantum-dot spin qubits enabled by extreme-ultraviolet lithography
Thomas Van Caekenberghe, Paul Steinacker, Bart Raes +31
The realization of large-scale silicon quantum processors requires spin qubits compatible with advanced semiconductor manufacturing technologies, demanding lithographic processes t…
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…
Modeling of flopping-mode spin qubits: beyond the two-site model
Ashutosh Kinikar, Vukan Levajac, Kristof Moors +3
We present a flexible modeling framework for flopping-mode spin qubits that captures the spatial structure of the double-well confinement and magnetic-field-gradient profile going…
Long coherence silicon spin qubit fabricated in a 300 mm industrial foundry
Petar Tomić, 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…
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…
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…
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…
Supercurrent in the presence of direct transmission and a resonant localized state
Vukan Levajac, Hristo Barakov, Grzegorz P. Mazur +4
We study the current-phase relation (CPR) of an InSb-Al nanowire Josephson junction in parallel magnetic fields up to \,mT. At high magnetic fields and in narrow voltage inter…
Subgap spectroscopy along hybrid nanowires by nm-thick tunnel barriers
Vukan Levajac, Ji-Yin Wang, Grzegorz P. Mazur +8
Tunneling spectroscopy is widely used to examine the subgap spectra in semiconductor-superconductor nanostructures when searching for Majorana zero modes (MZMs). Typically, semicon…
