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…
Strategies for enhancing spin-shuttling fidelities in Si/SiGe quantum wells with random-alloy disorder
Merritt P. Losert, Max Oberländer, Julian D. Teske +5
Coherent coupling between distant qubits is needed for any scalable quantum computing scheme. In quantum dot systems, one proposal for long-distance coupling is to coherently trans…
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…
