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…
Spin precession and laser-induced spin-polarized photocurrents
Esteban A. Rodríguez-Mena, Matías Berdakin, Luis E. F. Foa Torres
Controlling spin currents in topological insulators (TIs) is crucial for spintronics but challenged by the robustness of their chiral edge states, which impedes the spin manipulati…
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…
