In-situ control of hole-spin driving mechanisms
Simon Geyer, Rafael S. Eggli, Carlos dos Santos +6
Hole-spin qubits enable fast, all-electrical spin manipulation through electric-dipole spin resonance (EDSR), arising from two microscopic mechanisms rooted in their intrinsically…
Phase driving hole spin qubits
Stefano Bosco, Simon Geyer, Leon C. Camenzind +7
The spin-orbit interaction in spin qubits enables spin-flip transitions, resulting in Rabi oscillations when an external microwave field is resonant with the qubit frequency. Here,…
Cryogenic hyperabrupt strontium titanate varactors for sensitive reflectometry of quantum dots
Rafael S. Eggli, Simon Svab, Taras Patlatiuk +8
Radio frequency reflectometry techniques enable high bandwidth readout of semiconductor quantum dots. Careful impedance matching of the resonant circuit is required to achieve high…
A compact and versatile cryogenic probe station for quantum device testing
Mathieu de Kruijf, Simon Geyer, Toni Berger +4
Fast feedback from cryogenic electrical characterization measurements is key for the development of scalable quantum computing technology. At room temperature, high-throughput devi…
Two-qubit logic with anisotropic exchange in a fin field-effect transistor
Simon Geyer, Bence Hetényi, Stefano Bosco +7
Semiconductor spin qubits offer a unique opportunity for scalable quantum computation by leveraging classical transistor technology. Hole spin qubits benefit from fast all-electric…
Identifying Pauli spin blockade using deep learning
Jonas Schuff, Dominic T. Lennon, Simon Geyer +9
Pauli spin blockade (PSB) can be employed as a great resource for spin qubit initialisation and readout even at elevated temperatures but it can be difficult to identify. We presen…
Cross-architecture Tuning of Silicon and SiGe-based Quantum Devices Using Machine Learning
B. Severin, D. T. Lennon, L. C. Camenzind +20
The potential of Si and SiGe-based devices for the scaling of quantum circuits is tainted by device variability. Each device needs to be tuned to operation conditions. We give a ke…
A hole spin qubit in a fin field-effect transistor above 4 kelvin
Leon C. Camenzind, Simon Geyer, Andreas Fuhrer +3
The greatest challenge in quantum computing is achieving scalability. Classical computing previously faced a scalability issue, solved with silicon chips hosting billions of fin fi…
Silicon quantum dot devices with a self-aligned second gate layer
Simon Geyer, Leon C. Camenzind, Lukas Czornomaz +5
We implement silicon quantum dot devices with two layers of gate electrodes using a self-alignment technique, which allows for ultra-small gate lengths and intrinsically perfect la…
