Gate-defined quantum dot and charge noise analysis in a Forksheet transistor
Dominic Leclerc, Claude Rohrbacher, Alexis Morel +6
We report the cryogenic characterization of a 14-nm nMOS Forksheet transistor down to 10 mK. We demonstrate that the device retains transistor operation with improved characteristi…
Gate Synthesis in Dephasing-Limited Nitrogen-Vacancy Ensembles
Ankita Chakravarty, Arnaud Carignan-Dugas, Eva Dupont-Ferrier +1
Ensemble nitrogen-vacancy (NV) centers are widely used for quantum sensing and magnetometry, where performance depends on the accurate implementation of microwave pulse sequences.…
Multimode RF Reflectometry for Spin Qubit Readout and Device Characterization
Joffrey Rivard, Alexis Morel, Olivier Romain +10
We introduce a multimode superconducting inductor architecture that enables radio-frequency reflectometry at multiple discrete frequencies up to 2 GHz, addressing limitations of co…
Rapid Autotuning of a SiGe Quantum Dot into the Single-Electron Regime with Machine Learning and RF-Reflectometry FPGA-Based Measurements
Marc-Antoine Roux, Joffrey Rivard, Victor Yon +18
Spin qubits need to operate within a very precise voltage space around charge state transitions to achieve high-fidelity gates. However, the stability diagrams that allow the ident…
Robust quantum dots charge autotuning using neural network uncertainty
Victor Yon, Bastien Galaup, Claude Rohrbacher +10
This study presents a machine-learning-based procedure to automate the charge tuning of semiconductor spin qubits with minimal human intervention, addressing one of the significant…
Dual Operation of Gate-All-Around Silicon Nanowires at Cryogenic Temperatures: FET and Quantum Dot
C. Rohrbacher, J. Rivard, R. Ritzenthaler +5
As CMOS structures are envisioned to host silicon spin qubits, and for co-integrating quantum systems with their classical control blocks, the cryogenic behaviour of such structure…
