Valley Splittings in Si/SiGe Heterostructures from First Principles
Lukas Cvitkovich, Tancredi Salamone, Christoph Wilhelmer +3
We compute valley splittings in Si/SiGe superlattices using ab initio density functional theory (DFT). This first-principle approach is expected to provide an excellent description…
Valley physics in the two bands model for SiGe heterostructures and spin qubits
Tancredi Salamone, Biel Martinez Diaz, Jing Li +2
We discuss the choice and implementation of inter-valley potentials in the so-called two bands model for the opposite , or valleys of silicon…
Sweet-spot protection of hole spins in sparse arrays via spin-dependent magnetotunneling
Esteban A. Rodríguez-Mena, Biel Martínez, Ahmad Fouad Kalo +2
Recent advances in the scaling of spin qubits have led to the development of sparse architectures where spin qubits are distributed across multiple quantum dots. This distributed a…
Variability of hole spin qubits in planar Germanium
Biel Martinez, Yann-Michel Niquet
Hole spin qubits in Ge/GeSi heterostructures benefit from the clean environment of epitaxial interfaces and from the intrinsic spin-orbit coupling that enables efficient electrical…
Hole spin qubits in unstrained Germanium layers
Lorenzo Mauro, Mauricio J. Rodriguez, Esteban A. Rodriguez-Mena +1
Strained germanium heterostructures are one of the most promising material for hole spin qubits but suffer from the strong anisotropy of the gyromagnetic factors that hinders the o…
Dressed basis sets for the modeling of exchange interactions in double quantum dots
Mauricio J. Rodríguez, Esteban A. Rodríguez-Mena, Ahmad Fouad Kalo +1
We discuss the microscopic modeling of exchange interactions between double semiconductor quantum dots used as spin qubits. Starting from a reference full configuration interaction…
