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…
Long distance spin shuttling enabled by few-parameter velocity optimization
Alessandro David, Akshay Menon Pazhedath, Lars R. Schreiber +3
Spin qubit shuttling via moving conveyor-mode quantum dots in Si/SiGe offers a promising route to scalable miniaturized quantum computing. Recent modeling of dephasing via valley d…
Scalable Parity Architecture With a Shuttling-Based Spin Qubit Processor
Florian Ginzel, Michael Fellner, Christian Ertler +3
Motivated by the prospect of a two-dimensional square-lattice geometry for semiconductor spin qubits, we explore the realization of the Parity Architecture with quantum dots (QDs).…
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…
