Singlet-triplet oscillations in multivalley Si double quantum dots
Łukasz Cywiński, Mats Volmer, Tom Struck +2
Charge separation from the to the state in a Si/SiGe double quantum dot is commonly used for initialization of spin qubits and Pauli-spin-blockade readout. It was u…
Mapping g-factors and complex intervalley coupling in Si/SiGe by conveyor-mode shuttling
Mats Volmer, Tom Struck, Arnau Sala +7
As silicon spin qubit chips are increasing in qubit number and area, methods for the screening of qubit related material parameters become vital. Here we demonstrate the two-dimens…
Impact of the local valley splitting on the coherence of conveyor-belt spin shuttling in Si/SiGe
Mats Volmer, Tom Struck, Jhih-Sian Tu +6
Silicon quantum chips offer a promising path toward scalable, fault-tolerant quantum computing, with the potential to host millions of qubits. However, scaling up dense quantum-dot…
Mapping of valley-splitting by conveyor-mode spin-coherent electron shuttling
Mats Volmer, Tom Struck, Arnau Sala +10
In Si/SiGe heterostructures, the low-lying excited valley state seriously limit operability and scalability of electron spin qubits. For characterizing and understanding the local…
Spin-EPR-pair separation by conveyor-mode single electron shuttling in Si/SiGe
Tom Struck, Mats Volmer, Lino Visser +7
Long-ranged coherent qubit coupling is a missing function block for scaling up spin qubit based quantum computing solutions. Spin-coherent conveyor-mode electron-shuttling could en…
Si/SiGe QuBus for single electron information-processing devices with memory and micron-scale connectivity function
Ran Xue, Max Beer, Inga Seidler +6
The connectivity within single carrier information-processing devices requires transport and storage of single charge quanta. Our all-electrical Si/SiGe shuttle device, called quan…
Conveyor-mode single-electron shuttling in Si/SiGe for a scalable quantum computing architecture
Inga Seidler, Tom Struck, Ran Xue +4
Small spin-qubit registers defined by single electrons confined in Si/SiGe quantum dots operate successfully and connecting these would permit scalable quantum computation. Shuttli…
Robust and fast post-processing of single-shot spin qubit detection events with a neural network
Tom Struck, Javed Lindner, Arne Hollmann +4
Establishing low-error and fast detection methods for qubit readout is crucial for efficient quantum error correction. Here, we test neural networks to classify a collection of sin…
Low-frequency spin qubit detuning noise in highly purified Si/SiGe
Tom Struck, Arne Hollmann, Floyd Schauer +8
The manipulation fidelity of a single electron qubit gate-confined in a Si/SiGe quantum dot has recently been drastically improved by nuclear isotope purification. Here, we…
Large, tunable valley splitting and single-spin relaxation mechanisms in a Si/SiGe quantum dot
Arne Hollmann, Tom Struck, Veit Langrock +8
Valley splitting is a key figure of silicon-based spin qubits. Quantum dots in Si/SiGe heterostructures reportedly suffer from a relatively low valley splitting, limiting the opera…
