QArray+: A physics-informed GPU-accelerated simulator for quantum dot arrays
Pranav Vaidhyanathan, Barnaby van Straaten, Alice Petrillo +6
Semiconductor quantum-dot arrays are a compelling platform for scalable quantum technologies, yet their practical operation is hindered by the complexity of tuning large-scale devi…
Optimising germanium hole spin qubits with a room-temperature magnet
Cecile X. Yu, Barnaby van Straaten, Alexander S. Ivlev +6
Germanium spin qubits exhibit strong spin-orbit interaction, which allow for high-fidelity qubit control, but also provide a strong dependence on the magnetic field. Superconductin…
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…
QArray: a GPU-accelerated constant capacitance model simulator for large quantum dot arrays
Barnaby van Straaten, Joseph Hickie, Lucas Schorling +3
Semiconductor quantum dot arrays are a leading architecture for the development of quantum technologies. Over the years, the constant capacitance model has served as a fundamental…
Fully autonomous tuning of a spin qubit
Jonas Schuff, Miguel J. Carballido, Madeleine Kotzagiannidis +14
Spanning over two decades, the study of qubits in semiconductors for quantum computing has yielded significant breakthroughs. However, the development of large-scale semiconductor…
Automated long-range compensation of an rf quantum dot sensor
Joseph Hickie, Barnaby van Straaten, Federico Fedele +6
Charge sensing is a sensitive technique for probing quantum devices, of particular importance for spin qubit readout. To achieve good readout sensitivities, the proximity of the ch…
High-fidelity operation and algorithmic initialisation of spin qubits above one kelvin
Jonathan Y. Huang, Rocky Y. Su, Wee Han Lim +23
The encoding of qubits in semiconductor spin carriers has been recognised as a promising approach to a commercial quantum computer that can be lithographically produced and integra…
All rf-based tuning algorithm for quantum devices using machine learning
Barnaby van Straaten, Federico Fedele, Florian Vigneau +7
Radio-frequency measurements could satisfy DiVincenzo's readout criterion in future large-scale solid-state quantum processors, as they allow for high bandwidths and frequency mult…
Measurement cost of metric-aware variational quantum algorithms
Barnaby van Straaten, Bálint Koczor
Variational quantum algorithms are promising tools for near-term quantum computers as their shallow circuits are robust to experimental imperfections. Their practical applicability…
