Nuclear State Preparation via Landau-Zener-Stueckelberg transitions in Double Quantum Dots
Hugo Ribeiro, Guido Burkard
We theoretically model a nuclear-state preparation scheme that increases the coherence time of a two-spin qubit in a double quantum dot. The two-electron system is tuned repeatedly…

Bound states and magnetic field-induced valley splitting in gate-tunable graphene quantum dots
Patrik Recher, Johan Nilsson, Guido Burkard +1
The magnetic field dependence of energy levels in gapped single- and bilayer graphene quantum dots (QDs) defined by electrostatic gates is studied analytically in terms of the Dira…
