Eight-Qubit Operation of a 300 mm SiMOS Foundry-Fabricated Device
Andreas Nickl, Nard Dumoulin Stuyck, Paul Steinacker +24
Silicon spin qubits are a promising platform for quantum computing due to their high coherence, controllability, and CMOS manufacturability, yet scalable implementations have so fa…
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…
Engineering high Pockels coefficients in thin-film strontium titanate for cryogenic quantum electro-optic applications
Anja Ulrich, Kamal Brahim, Andries Boelen +13
Materials which exhibit the Pockels effect are notable for their strong electro-optic interaction and rapid response times and are therefore used extensively in classical electro-o…
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…
A 300 mm foundry silicon spin qubit unit cell exceeding 99% fidelity in all operations
Paul Steinacker, Nard Dumoulin Stuyck, Wee Han Lim +24
Fabrication of quantum processors in advanced 300 mm wafer-scale complementary metal-oxide-semiconductor (CMOS) foundries provides a unique scaling pathway towards commercially via…
