Machine Learning for Charge State Characterization of Isolated Double Quantum Dots
Hyma Vallabhapurapu, Marco Candido, Krishna Choudhary +7
Scaling semiconductor quantum dot arrays toward fault-tolerant quantum computing requires efficient tuneup of spin qubits, a process that depends on the analysis of charge stabilit…
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…
Optimal operating temperature for industry-compatible silicon spin quantum computing: colder is not necessarily better
Paul Steinacker, Amanda E. Seedhouse, Nard Dumoulin Stuyck +22
The paper experimentally benchmarks silicon spin qubits over a range of temperatures and models the trade‑off between gate fidelity and cooling power, showing that a finite optimal…
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…
Gate Stack Engineering for High-Mobility and Low-Noise SiMOS Quantum Devices
Md. Mamunur Rahman, Ensar Vahapoglu, Kok Wai Chan +16
We systematically investigate the interplay between materials engineering, quantum transport, and low-frequency charge noise in silicon metal--oxide--semiconductor (SiMOS) quantum…
Electrical driving of hole spin states in planar silicon MOS device by g-matrix modulation
Aaquib Shamim, Scott D. Liles, Joe Hillier +10
Hole spins in group IV quantum dots are a highly promising way to develop CMOS compatible spin qubits owing to their inherent spin-orbit coupling, which enables fast, coherent, and…
