Non-perturbative theory of valley splitting in Si qubits from variational wave function: periodic effects of shear strain and asymptotic freedom in the wiggle-well potential
Johannes L. P. Steinschuld, Hendrik J. Bluhm, Seyed Akbar Jafari
Valley splitting sets the energy scale at which spin and valley degrees of freedom hybridize in silicon quantum-well qubits, but its sensitivity to interface structure makes it dif…
Valley-Enabled Intrinsic Dresselhaus Spin-Orbit Coupling in Silicon
Johannes L. P. Steinschuld, Hendrik J. Bluhm, Lars R. Schreiber +1
We develop a symmetry-based theory of spin-orbit-valley coupling in silicon that reveals an intrinsic source of Dresselhaus spin-orbit coupling independent of interfaces or externa…
Enhanced intrinsic spin-orbit driving of a Loss-DiVincenzo qubit near the spin-valley hotspot in Si/SiGe
Alexander Willmes, Max Oberländer, Max Beer +7
In most Si/SiGe-based spin qubit implementations, high-fidelity single-qubit gates are achieved using micromagnets, which enable the use of electric spin dipole resonance via synth…
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…
Conveyor-mode electron shuttling through a T-junction in Si/SiGe
Max Beer, Ran Xue, Lennart Deda +6
Conveyor-mode shuttling in gated Si/SiGe devices enables adiabatic transfer of single electrons, electron patterns and spin qubits confined in quantum dots across several microns w…
