Spin-cQED with bulk germanium spin qubits
A. -F. Kalo, E. A. RodrÃguez-Mena, J. C. Abadillo-Uriel +2
Unstrained bulk germanium is a particularly attractive material for circuit quantum electrodynamics with spins (spin-cQED). We show, through systematic modeling and comparison with…

Sweet-spot protection of hole spins in sparse arrays via spin-dependent magnetotunneling
Esteban A. RodrÃguez-Mena, Biel MartÃnez, 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…

Dressed basis sets for the modeling of exchange interactions in double quantum dots
Mauricio J. RodrÃguez, Esteban A. RodrÃguez-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…
